摘要
High-field magnetization process of the single crystal of Er2Fe17H3 is investigated and compared with that of the parent Er2Fe17 in order to clarify the effect of interstitial hydrogen on magnetic properties. Substantial change in the magnetic anisotropy behavior observed for Er2Fe17H3 is explained by the modification of the interaction between the 4f-shell orbital moment of Er and the crystal field leading to the change of the second-order crystal electric field coefficient A(2)(0). Hydrogenation does not practically affect the intersublattice molecular field.
