- Аннотация: The magnetocrystalline anisotropy of R 2Fe 17 (R=Y, Gd, Tb, Ho and Er) and their hydrides are studied by analyzing the magnetization curves of single crystal samples in the temperature range 4.2-300 K in magnetic fields up to 140 kOe. There is no noticeable influence of hydrogenation on the magnetic anisotropy in the Y 2Fe 17 and Gd 2Fe 17 compounds. An easy-plane to easy-cone transition is detected for a Tb 2Fe 17H 3 single crystal after hydrogenation. A significant change of the magnetization process has been observed in the hydrides Ho 2Fe 17H 3 and Er 2Fe 17H 3. Hydrogenation induces a FOMP-type transition in the Ho 2Fe 17H 3 compound and, on the contrary, leads to the disappearance of the FOMP type transition in the Er 2Fe 17H 3 compound. The obtained results are discussed on the basis of a model based on the interaction of the quadrupolar moment and the magnetic moment of the 4f electron shell of the rare earth ion with the interstitial hydrogen. It is established that the orientation of the quadrupolar moment of the asymmetric 4f shell with respect to the direction of the resulting magnetic moment of 4f electrons plays an important role. © 2002 Elsevier Science B.V.
