| 中文摘要 | Ce(Cu1-xGax)2 compounds with x = 0.0, 0.2, 0.4, 0.6, 0.75 and 1.0 were prepared and found to crystallize in the orthorhombic CeCU2 Structure up to the composition x = 0.6, whereas for higher Ga content the hexagonal AlB2 structure is formed. We report on specific-heat, electrical-resistivity and magnetic-susceptibility measurements. Furthermore, the specific heat was measured in magnetic fields up to 5 T and the development of the magnetic moments and the magneto-crystalline anisotropy were studied measuring the high-field magnetization in magnetic fields up to 35 T. For CeCu2-based compounds, the high-field magnetization results reveal a decrease of the ordered moment with increasing Ga content, which can be understood in terms of an increased 4f-ligand hybridization. The strong magnetocrystalline anisotropy observed in all samples changes from uniaxial type for x less-than-or-equal-to 0.2 to multiaxial type for x > 0.2. Specific-heat measurements reveal the temperatures of magnetic ordering first to decrease from 3.5 K for CeCu2 to a temperature below 1.3 K for CeCu1.6Ga0.4 and then to increase again to 2.1 K for CeCu0.8Ga1.2. A development of Kondo-like behaviour was observed in the electrical resistivity. |
