Stashkova, V. Gaviko, N. Mushnikov, P. Terent'ev] X-ray diffraction studies of rare-earth intermetallic Er1 − x Tb x Fe2 compounds (with 0 ≤ x ≤ 0.6) and their hydrides were performed at room temperature. As the terbium content (x) in Er1 − x Tb x Fe2 increases, the sign of the magnetostriction constant λ111 was shown to alternate from positive to negative. The lattice parameters, amount of incorporated hydrogen, and sizes of interstices were found to increase with increasing terbium content. The sizes of interstices accessible for occupation with hydrogen atoms were calculated for all alloys and their hydrides. Spontaneous anisotropic magnetostriction related to the rare-earth atoms was found to make no determining contribution to the resulting crystal lattice distortion caused by the incorporation of hydrogen atoms.
