Abstract

The cubic compound YbCo₂Zn₂₀ has huge electronic specific heat coefficient γ=7900 mJ/molK² and its ground state could be located in the vicinity of the quantum critical point. To investigate magnetic ground state, we have carried out muon spin relaxation measurements and confirmed non-magnetic ground state with fluctuating tiny magnetic moment.

Abstract
Eu₂Mg₄Si₃ ≡ (2Eu²⁺)(4Mg²⁺)(3Si⁴⁻) is an electron-precise Zintl phase. Its Hf₂Co₄P₃-type structure contains three crystallographically independent europium sites. The divalent state of europium was manifested through ¹⁵¹Eu Mössbauer spectroscopy. In the paramagnetic regime (T = 78 K) the isomer shifts range from −9.16 to −11.29 mm s⁻¹. Eu₂Mg₄Si₃ shows complex magnetic hyperfine field splitting at T = 5.7 K with a superposition of three subspectra with magnetic hyperfine fields of 5.4 (Eu2), 20.4 (Eu1) and 22.4 (Eu3) T.

We report a uniaxial pressure-dependence of magnetism in layered perovskite strontium ruthenate Sr3Ru2O7. By applying a relatively small uniaxial pressure, greater than 0.1 GPa normal to the RuO2 layer, ferromagnetic ordering manifests below 80 K from the enhanced-paramagnet. Magnetization at 1 kOe and 2 K becomes 100 times larger than that under ambient condition. Uniaxial pressure dependence of Curie temperature $T_{\text{C } }$ suggests the first order magnetic transition. Origin of this uniaxial-pressure induced ferromagnetism is discussed in terms of the rotation of RuO6 octahedra within the RuO2 plane.

The magnetic properties of a single-crystalline sample Ce2Sc3Ge4 have been investigated, for the first time. On the basis of the magnetization, magnetic susceptibility, electrical resistivity and specific heat measurements, we suggest that Ce2Sc3Ge4 is an antiferromagnetic Kondo compound with $T_{\text{N } } = 5.0$ K. The saturated magnetic moment for the Ce atom is estimated to be 1.1$\mu_{\text{B } }$ at $T = 1.5$ K by the magnetization measurements. Electronic specific heat coefficient $\gamma$ is estimated to be 49.5 mJ/molK2, indicating that the system is described as a medium-heavy fermion compound.

We have investigated two-dimensional spin systems SrCu_2(BO_3)_2 and Nd_2BaZnO_5, both of which have a unique topology that is equivalent to the Shastry-Sutherland lattice. The magnetization curve of SrCu_2(BO_3)_2 reveals that, unlike 1/8 and 1/4 plateaux, a 1/3 plateau is very stable, surviving at least up to 69 T. The pressure dependence of susceptibility up to 10 kbar indicates that the pressure causes the system to approach the critical point to some other states. On the other hand, Nd_2BaZnO_5 with rather classical spins exhibits an antiferromagnetic long range ordering at 2.4 K. Finally, other experimental candidates of extended Shastry-Sutherland system will be briefly presented.

We developed a method of precise measurement of the dielectric constant under multi-extreme conditions, that is, under high pressures, high magnetic fields and low temperatures. We measured the dielectric constants and the magnetic susceptibility of single crystals of α′-NaV2O5 under multi-extreme conditions. Anisotropic behavior of a relative dielectric constant was observed at the charge-ordering transition temperature under ambient pressure. With increasing hydrostatic pressure, the transition temperature decreased and another transition appeared below the first transition temperature. The susceptibility exhibited a sharp drop corresponding to the transition to the spin singlet state at the first transition temperature, while it showed no anomaly at the second transition temperature. These two transition temperatures were found to exhibit very weak magnetic field dependence in comparison with typical spin-Peierls compounds.

Magnetization of Eu_0.58Sr_0.42MnO₃ was measured under hydrostatic pressures up to 0.8 GPa in order to investigate the effect of pressure on the metal-insulator transition, which was investigated at high pressure by resistivity measurements. At ambient pressure, below about 45 K, the magnetization vs temperature curve reveals a spin-glass behavior as reported for a previous experiment. With increasing pressure, the magnetization increases at both 0.005 T and 0.5 T, and a cluster-glass behavior appears at 0.5 T above 0.37 GPa. On the other hand, the magnetization increases with increasing pressure at 1.5 T and 5.0 T. We also found that the high-field susceptibility increases linearly with increasing pressure at a rate of (dχ_hf/dp) = 0.0336(6)μ_BT^-1 GPa^-1.

We report the observation of an unexpected magnetic transition in the Kondo semimetal CeNiSn under uniaxial pressures. For P∥a, both the specific heat C and magnetic susceptibility χ decrease steadily with increasing P. By contrast, once P∥b and P∥c exceed 0.13 GPa, C(T) exhibits a distinct jump at 4 K followed by a peak at 3 K. The concomitant peaking in χ(T) for P∥B∥c is indicative of an antiferromagnetic transition.

Jc Measurements and the Observation of Flux Movements and Flux Jumps in Quench-and-Melt Growth YBCO by a Pulsed Magnetic-Field　　　　　　　　　　　　　　　
T. Takizawa; M. Kosaka; K. Kanbara; M. Morita; K. Sawano
Japanese Journal of Applied Physics, Volume：30, Number：10, First page：L1790, Last page：L1793, 1991, [Reviewed]
An observation of the flux motion in a ring-shaped quench-and-melt growth (QMG) YBCO has been attempted under a pulsed magnetic field in a temperature range from $T_{\text{c } }$ down to 25 K. The transport critical current density ($J_{\text{c } }$) is estimated from the magnetic field where the flux just enters into the central hole of the sample ring. At low temperatures, the flux jump is clearly observed and its interpretation is made in terms of the traditional stabilization theory. In a thin sample, a peculiar flux motion suggesting the undulation of flux lines is observed.

六方晶希土類化合物のSmPtPはR = Gd-Luのランタノイド収縮から外れている。同じくランタノイド収縮に従わないR = Eu は結晶の周期構造の変化と共に価数の秩序状態が変化し、結晶の周期性と価数の関係が注目されている。今回、SmPtPのX線回折の結果からc軸に他の希土類の4倍の長周期性を発見した。さらに、磁化測定から見積もった有効ボーア磁子と飽和磁化の値からは価数混合状態が示唆される。電気抵抗、比熱測定の結果と共に結晶の周期構造とSmの価数状態の関係に注目した講演を行う。

High-pressure apparatuses have been designed to measure the electrical and magnetic properties of condensed matters. The apparatuses for electrical and magnetic measurements can be used at least up to 33 kbar at down to 1.5 K and 12 kbar at down to 1.8 K with SQUID Magnetometer (by Quantum Design), respectively. Applications of these apparatuses to measure the electrical resisivity and magnetizationfor YbInCu4 are briefly described.

A quantum spin liquid state, which shows the strong correlation among the spins but does not order magnetically even at absolute zero temperature, is regarded as a new magnetic state. We synthesized the insulating compound KYbS2, where Yb3+ ions with the effective spin-1/2 form a two-dimensional triangular lattice. From our measurements in the low temperature region, we have demonstrated that KYbS2 is the spin liquid candidate. Furthermore, we also found that YbAgS2 shows the development of short-range magnetic correlations, which arises from one-dimensional chains of Yb3+ ions.

We found that the intermetallic compound Yb5Ge4 indicates the development of short-range correlations caused by magnetic frustration. Yb5Ge4 is the mother material of Yb4LiGe4, which is designed to reinforce the magnetic frustration effects performed by the Li-substitution. The diffraction anomalous fine structure method (DAFS), X-ray structural technique, reveals one of three crystallographic sites of Yb ions occupies the Yb3+ state and the other sites are in the Yb2+ state. The valence-ordered state already realizes at room temperatures, therefore, the low-dimensional magnetic network has been formed by Yb3+ ions. The anomalous behaviors in the temperature dependences of magnetization and specific heat of Yb5Ge4 are due to the development of short-range magnetic correlations, which arises from low-dimensionality effects of magnetic interactions.

We found that the intermetallic compound YbAl_3C_3 exhibits an spin-singlet ground state at low temperatures. The structure of the first excited triplet state, which develops rapidly below 10K, is directly clarified by inelastic neutron scattering experiments with a higher energy resolution. The spin-singlet ground state has never been observed in 4f electron systems. The two-dimensional frustrated triangular lattice and the low carrier density play an important role in the realization of the spin-singlet ground state. In order to investigate physical properties of YbAl_3C_3, we have performed synchrotron X-ray diffraction, NMR・NQR, specific heat, magnetization, electrical resistivity and elastic constant measurements.
