通过磁化率、磁化率、比热和电阻率等测试，研究了立方金属间化合物ndcu4ag单晶的磁性能。在4.2 K时，C (T)中有一个尖峰26 J/(mol K)的异常，同时有χ(T)的反铁磁行为，表明在该温度下发生了反铁磁相变。分别在[001]、[110]和[111]方向研究了外场M (H)、χ(T)和C (T)的各向异性。在三个方向施加磁场时，在尼尔温度T N以下观察到两次变磁转变。在三个方向上，T N均随磁场的增大而减小，在χ(T)和C (T)中均观察到高H ext引起的新异常，表明两个新磁相与反铁磁相共存。根据比热测量，推测晶体电场…
The magnetic properties of cubic intermetallic compound NdCu 4 Ag single crystals were studied in detail through magnetization, susceptibility, specific heat and electrical resistivity measurements. An observed anomaly in C ( T ) with a sharp peak 26 J/(mol K) at 4.2 K, together with an antiferromagnetic behavior of χ( T ), indicated that an antiferromagnetic phase transition occurred at this temperature. Anisotropic properties in M ( H ), χ( T ), and C ( T ) at external fields were investigated in directions of [001], [110], and [111], respectively. Two metamagnetic transitions were observed below the Neel temperature T N when a magnetic field was applied in three directions. In all the three directions, T N decreased with an increase in magnetic field and new anomalies induced by a high H ext were observed in both χ( T ) and C ( T ), implying that two new magnetic phases coexisted with the antiferromagnetic phase. From the specific heat measurements, it is speculated that the crystalline electric field ...
