    We have investigated synthesis conditions and magnetic properties of Sr2Fe2+2Fe3+12O22 (Sr2Fe2Y). The main Y-type phase was observed for the sample synthesized with the initial composition of Sr:Fe2+:Fe3+=1.5:2:8 sintered at TS=1200℃ and PO2=10 Pa. The Curie temperature of Sr2Fe2Y was 643 K. The magnetization was 45.0 Am2/kg at T= 5 K and μ0H=7 T. The difference in magnetization from the ideal collinear spin arrangement of Sr2Fe2Y is due to the existence of a minor Fe3O4-like spinel phase. The yield of Sr2Fe2Y phase was estimated to be 83 wt.%, suggesting successful synthesis of the Sr2Fe2Y hexaferrite.

    We investigated the synthesis conditions and magnetic properties of Fe substituted hibonite with initial compositions of CaAlxFey−xO19−δ (1 ≤ x ≤ 3, 5 ≤ y ≤ 9) and CaAlxFe8-xO19−δ (0.5 ≤ x ≤ 1.6) sintered at 1200–1300ºC. The optimum conditions for synthesizing the best magnetic hibonite were found to be the initial composition of Ca:Al:Fe = 1:0.6:7.4 and the sintering temperature of 1250ºC. The best magnetic hibonite was magnetized at 75.0 A·m2/kg at T = 5 K and μ0H = 7 T. This magnetic moment can be interpreted with a model of the collinear magnetic structure. The Curie temperature of the best magnetic hibonite was 330ºC, which was the highest among those of iron-substituted hibonite samples.

    We have investigated the synthesis conditions and magnetic properties of Fe substituted hibonite with initial compositions of CaAl12-xFexO19 (0≤x≤12) and CaAl10-xFexO19-δ (0≤x≤10). The Fe doped hibonite can be synthesized at a sintering temperature of 1300˚C. The X-ray diffraction patterns of Fe substituted hibonite samples are in good agreement with the pattern of hibonite. The lattice parameter increased due to the difference between the radius of Al3+ and that of Fe3+. The magnetization and Curie temperature of the best sample (CaAl2Fe8O19-δ) are 31 emu/g and 290˚C, respectively.

    We investigated synthesis conditions and magnetic properties of Fe-deficient Ca-based hexagonal ferrites, Ca1−xLaxFeyO19−σ (x = 0.1–0.3, y = 2.0–10), and found the formation of M-type ferrite at x = 0.1–0.3 and y = 7.0–9.0 above 1200°C. Samples of y = 2.0–6.0 showed deviation from the initial compositions since molten calcium-rich oxide (possibly CaFe2O4) leaked out from the samples above 1200°C. The X-ray diffraction pattern of Ca0.8La0.2Fe8.0O19−σ sintered at 1250°C demonstrates the single phase of M-type hexagonal ferrite. The saturation magnetization of this sample was 68.0 Am2/kg at room temperature and its Curie temperature was about 400°C, which is slightly lower than that of the Sr-based M-type ferrite (460°C).

    We investigated the synthesis conditions and magnetic properties of non-magnetic-ion-substituted Ca-based hexagonal ferrites, Ca0.8La0.2Fe8.0−2xMgxTixO19−σ (x = 0.1–3.5) and Ca0.8La0.2Fey−xAlxO19−σ (x = 1.0–5.0, y = 8.0–10). We found that Mg-Ti-substituted Ca-based M-type ferrites formed at x = 0.1 and 0.2 at above 1225ºC. The sample at x = 0.1 showed the crystallographic single phase of M-type ferrite. The minimum Curie temperature of the Mg-Ti-substituted samples was 367ºC. Also, we found that the Al-substituted Ca-based M-type ferrites had the main phase of M-type ferrite in all samples. As the amount of substituted Al increased, the saturation magnetization and the Curie temperature decreased, and the coercivity increased. As the amount of substituted Al increased by Δx = 1, the Curie temperature decreased by ΔTC = 50–70ºC. Al-substituted samples of x = 1.0 and 2.0 sintered at 1300ºC had the single phase of M-type ferrite.

  • Synthesis and Magnetic Properties of (Zn2+Ti4+) Substituted W-type and Y-type Ferrites　　　　　　　　　　　　　　　
    Watanabe K.; Kakizaki K.; Kamishima K.
    Journal of the Magnetics Society of Japan, Volume：41, Number：6, First page：127, Last page：131, 2017, [Reviewed], [Last, Corresponding]
    We report the synthesis of (Zn2+Ti4+) substituted hexagonal ferrites, BaZn2(Zn0.5Ti0.5)xFe16-xO27 (W-type) and Ba2Zn2(Zn0.5Ti0.5)xFe12-xO22 (Y-type), and the relationship between their composition and magnetic properties. Substituted W-type ferrite was synthesized in the region of 0.0 ≤ x ≤ 1.5. A decrease in the Curie temperature of the W-type phase indicated that the exchange interactions between the Fe3+ ions weakened due to the substitution of Zn2+ and Ti4+ ions. Spontaneous magnetization (σS) at x = 0.5 was similar to that at x = 0.0. This reflects the equal distribution of nonmagnetic Zn2+ and Ti4+ ions to spin down sites and spin up sites, respectively. At x > 0.5, σS decreased clearly, which was possibly caused by a deviation from the collinear arrangement. Substituted Y-type ferrite was also obtained up to x = 0.5. The Y-type phase is more unstable than the W-type phase with respect to this substitution rate.

    We have investigated the synthesis conditions, and the magnetic properties of BaFe2+2Fe3+16O27 (Fe2W) and Ba2Fe2+2Fe3+12O22 (Fe2Y). It is found that Fe2W can be synthesized at a sintering temperature of 1300°C and Fe2Y can be synthesized at a sintering temperature of 1000°C. The X-ray diffraction patterns for Fe2W and Fe2Y samples are in good agreement with the pattern of BaCo2+2Fe3+16O27 (Co2W) and that of Ba2Co2+2Fe3+12O22 (Co2Y). It is also found that the Curie temperatures of Fe2W and Fe2Y ferrites are 503 and 375°C, respectively.

    Ba3Co2Mn0.5xTi0.5xFe24-xO41 (x=0-0.6) samples were prepared by using a conventional ceramic method. The samples had a the single crystallographic phase of hexagonal Z-type ferrite, which suggests that Fe3+ ions are replaced by Mn2+ and Ti4+ ions. Substituted samples of Ba3Co2Mn0.5xTi0.5xFe24-xO41 with x=0.4 had a maximum μ' of 25.7 and a μ'×fr of 17.6 GHz. The M-T curves exhibited an anomalous drop below the Curie temperature, which reflects the change from in-plane magnetic anisotropy to uniaxial anisotropy with increasing temperature. The temperature of the anomalous drop rose from 533 K to 559 K due to the substitution. This resulted in an improvement of μ' and μ'×fr.

    Journal of the Magnetics Society of Japan, Volume：30, Number：3, First page：383, Last page：386, 2006, [Reviewed]
    Co-Zn-Ti substituted M-type barium ferrites of BaCoxTixFe12-2xO19 (x = 1−3 ) and BaCo1.1ZnyTi1.1+yFe9.8-2yO19 (y = 0−1.0) were prepared by a powder metallurgy method. Their characteristics were examined by using an X-ray diffractometer, a vibration sample magnetometer (VSM), a vector impedance analyzer, and a scanning electron microscope. When Fe ions of BaFe12O19 were replaced with Co-Ti ions, the magnetic anisotropy and coercivity decreased. As a result, the initial permeability increased to 27 for a sample with x = 1.15. Zn-Ti ions were also substituted for Fe ions in BaCo1.1Ti1.1Fe9.8O19. When the amount of substitution (y) was 0.4 in BaCo1.1ZnyTi1.1+yFe9.8-2yO19 (y = 0−1.0), the initial permeability at 10 MHz had a very high value of about 40. The reason for this may be that the coercivity becomes small as a result of the growth of the crystal particles and the decrease in the anisotropic magnetic field.

    We have attempted to obtain a bulk material including the sandwich structure made up of two conducting ferromagnetic layers separated by a thin insulating layer. The electric resistance between these ferromagnets will be increased by their antiparallel alignment in magnetization whereas reduced by their parallel alignment, leading to the expectation for application to electronics.
    We succeeded in the synthesis of new materials containing these kinds of layered structures. However, the magnetoresistance was affected by insulating layers between grains out of the crystal structure.

    We have attempted to obtain a chemically stable ferromagnet made up of inexpensive and safe elements. The application of sinusoidal magnetic fields can heat a ferromagnet. Therefore, the ferromagnet can be applied to the hyperthermia therapy that uses slightly higher temperatures to give damages to cancer cells.
    We succeeded in synthesis of a potassium lanthanum-iron oxide that had the comparable magnetization with that of iron oxide practical magnets. The magnetization was 59.6 emu/g at room temperature and 96.3 emu/g at 5 K.

  • Preparation of ferromagnetic pyrolytic carbon by heating under magnetic field and its physical properties

    We have prepared pyrolytic carbon samples from triethylamine by pyrolysis under high magnetic field up to 6 Tesla, and investigated their magnetic properties. Ferromagnetic samples were obtained from the pyrolysis products even at room temperature. The maximum spontaneous magnetization was 3.0 emu/g at 300K. The crystal structure was examined by the synchrotron X-ray diffraction experiment at SPring-8. The diffraction peak of diamond was observed for the ferromagnetic samples. Thus, it is possible that the ferromagnetic ordering of radical spins is caused by defects in the diamond structure. The diffraction peak intensity of diamond for the ferromagnetic samples increased with the applied magnetic field at sample preparation. Therefore, the magnetic field may help to form a three dimensional ferromagnetic structure in the carbon-based ferromagnet. A ferromagnetic sample with higher magnetization of 6.4emu/g at 300K was also obtained by field-pyrolysis with diamond powder under magnetic field of 6 Tesla. The crystal growth of the ferromagnetic pyrolytic carbon may be accelerated on the diamond powder, which is consistent with the above-mentioned synchrotron X-ray diffraction result.
