摘要：

We have succeeded in synthesizing Filled skutterudite-type structure compounds GdRu4P12 and TbRu4P12 under high pressure. The magnetic properties of GdRu4P12 and TbRu4P12 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 GdRu4P12 displays features that suggest the occurrence of antiferromagnetic ordering below T-N=22 K. In TbRu4P12, thermal variation of magnetic susceptibility indicates the existence of two successive magnetic transitions (T-N=20 K and T-1 = 10 K). Magnetization up to 18 T exhibits two-step metamagnetic transitions below T1 for TbRu4P12.
