Abstract
The ternary silicide CeCuSi, that crystallizes in the hexagonal ZrBeSi-type structure, absorbs hydrogen at 393 K and 2 MPa to form the stable hydride CeCuSiH1.35(10). Magnetization and electrical resistivity measurements reveal that CeCuSi orders ferromagnetically below Tc=15.2(2) K while its hydride exhibits a complex magnetic phase diagram with three transitions at 13.7(3), 10.6(3), and 8.4(3) K. This behavior could be explained by the more complex environments of Ce-atoms after hydriding that lead to a great hexagonal unit cell (a=4.194(1) Å and c=41.69(4) Å) deriving from that of ZrBeSi-type.
