Structural and high-field magnetic properties of Laves phase RFe2-H hydrides
Original language description
The crystal structure and magnetic properties of the multicomponent compounds (Tb1-xYx)0.8Sm0.2Fe2Hz are investigated. The compounds crystallize in the MgCu2 type of structure. Hydrogen absorption does not change the space group of (Tb,Y,Sm)Fe2 but boosts significantly the lattice parameter a. A large volume change of ΔV/V ∼28% upon hydrogen absorption is observed. By applying high magnetic fields up to 58 T, we observed rotations of the magnetic sublattices and hence we were able to determine the critical transition fields, H, from the ferrimagnetic to the ferromagnetic state and the inter-sublattice exchange parameter λ. The magnetic compensation occurs at x ≈ 0.6 and 0.2 in (Tb1-xYx)0.8Sm0.2Fe2Hz at z = 0 and 3.7, respectively. While maintaining the collinear magnetic structure, the phenomenon of compensation in hydrides should be observed at x ≈ 0.4.
