Abstract The magnetic properties of HoCo12B6 ferrimagnetic compound are investigated versus the magnetic field, temperature and pressure. The magnetic phase diagram exhibits three remarkable temperatures: the ordering temperature TC, the spin reorientation temperature TSR and the compensation temperature TCOMP at 147 K, 76 K and 47 K respectively. In HoCo12B6 intermetallic system the spontaneous magnetization resulting from the antiparallel coupling of the magnetic moments of Ho and Co sublattices is pressure insensitive at lowest temperatures whereas it decreases with pressure at temperature range above TSR. The mean Co magnetic moment is small (

HoCo12B6亚铁磁性化合物的磁性和相图的压力依赖性

摘要 研究了 HoCo12B6 亚铁磁性化合物与磁场、温度和压力的关系。磁相图表现出三个显着的温度：排序温度 TC、自旋重定向温度 TSR 和补偿温度 TCOMP，分别为 147 K、76 K 和 47 K。在 HoCo12B6 金属间化合物系统中，由 Ho 和 Co 亚晶格的磁矩反平行耦合产生的自发磁化强度在最低温度下对压力不敏感，而在高于 TSR 的温度范围内随压力降低。平均 Co 磁矩很小 (
