我们在高压下成功地合成了填充式方钴矿结构化合物GdRu 4P 12和TbRu 4P 12。通过电阻率、磁化率和磁化强度的测量，研究了GdRu 4P 12和TbRu 4P 12的磁性.磁性实验表明化合物中Gd和Tb离子均为三价态。化合物GdRu 4P 12在低于T N5 22 K时显示出反铁磁有序的特征.磁化率的热变化表明TbRu 4P 12存在两个连续的磁性转变~ TN 520 K和T1510 K！.磁化强度高达18 T表现出两步变磁转变低于T1的TbRu 4 P12。
We have succeeded in synthesizing filled skutterudite-type structure compounds GdRu 4 P 12 and TbRu 4 P 12 under high pressure. The magnetic properties of GdRu 4 P 12 and TbRu 4 P 12 have been studied by means of electrical resistivity, magnetic susceptibility, and magnetization measurements. Magnetic experiments suggest that the Gd and Tb ions in the compounds have trivalent state. The compound GdRu 4 P 12 displays features that suggest the occurrence of antiferromagnetic ordering below T N 5 22 K. In TbRu 4 P 12 , thermal variation of magnetic susceptibility indicates the existence of two successive magnetic transitions ~ T N 5 20 K and T 1 5 10 K ! . Magnetization up to 18 T exhibits two-step metamagnetic transitions below T 1 for TbRu 4 P 12 .
