摘要：

The ternary stannide CeNiSn absorbs hydrogen at 250 degreesC under a pressure Of P-H2 = 5 MPa. The resulting hydride CeNiSnH1.8(2) crystallizes in the hexagonal ZrBeSi-type structure with a = 0.4392(2) nm and c = 0.8543(2) nm as unit cell parameters. Investigation by means of magnetization and electrical resistivity measurements show that M CeNiSnH1.8(2) exhibits a ferromagnetic order below T-C = 7.00 K and GO Kondo scattering dominates the electrical properties. This study points out that hydrogenation of CeNiSn provokes a change of the ground state of cerium, from Kondo insulator to ferromagnetic behavior.
