The crystal structure and magnetic properties of the multicomponent Laves phase compounds (Gd1-xYx)0.85Sm0.2Fe2Hz (x = 0, 0.2, 0.4, 0.6, 0.8, 1, z = 0 and 3.4) are investigated. These compounds crystallize into an MgCu2 type of structure. Hydrogenation does not change the crystal structure type but boosts the unit cell volume of the compounds by ∼25%. Both parent and the hydrogen-charged ferrimagnetic compounds demonstrate magnetic compensation. The exact compositions with zero magnetization state (compensated compositions) predicted using a three-sublattice model are in good agreement with the experiment.
