measurements of LuCo3 and YCo3 single crystals. These compounds show an instability of the 3d-subsystem, whereby the Co atoms go from a low-spin to a high-spin state in applied magnetic field. In the low-spin state, we find a pronounced anisotropy of the saturation magnetization for LuCo3 and YCo3, which can potentially lead to a large error in the determination of the anisotropy constant, K2, whereas the
我们报告了 LuCo 3和 YCo 3单晶的磁化测量。这些化合物显示出 3 d子系统的不稳定性,由此 Co 原子在外加磁场中从低自旋状态变为高自旋状态。在低自旋状态下,我们发现 LuCo 3和 YCo 3的饱和磁化强度具有明显的各向异性,这可能会导致各向异性常数K 2的确定存在较大误差,而常数K 1,影响小很多。我们还表明,Belov-Arrott 图产生的居里温度值与通过沿不同结晶方向的磁化曲线获得的值不同。
