| Abstract: | The magnetic properties of the RY2Ni9 ternary alloys (R=La, Ce) and their hydrides have been investigated. Both LaY2Ni9 and CeY2Ni9 are ferromagnets with TC=15 and 92 K, respectively. Upon H absorption LaY2Ni9H12 becomes a Pauli paramagnet, whereas CeY2Ni9H8 remains ferromagnetic with an additional magnetic contribution of trivalent Ce atoms belonging to the MgZn2 units occupied by hydrogen atoms. |
