- Аннотация: The effects of hydrogen and nitrogen on the magnetic properties (the Curie temperatures, saturation magnetization, magnetocrystalline anisotropy, and magnetostriction) of RFe11Ti and R2Fe17 compounds are studied. Structural and magnetic investigations have been performed by means of X-ray diffraction, torque and pendulum magnetometer techniques, and high-field magnetization measurements on RFe11TiH1-δ and R2Fe17H3-δ single crystals and the magnetically aligned powder samples RFe11TiNX and R2Fe17NX. The hydrides and nitrides still retain the structure of their parent compounds, but the unit cell volumes are expanded. The Curie temperature is increased by both hydrogenation and nitrogenation. Magnetic phase diagrams of investigated compounds have been obtained. The sign of the effect of interstitial atoms on the magnetic anisotropy constants and spin-reorientation transitions is determined by the following three factors: (1) the type of the interstitial atoms; (2) the local surrounding of the R ions; and (3) the orientation of the quadrupole moment q of the asymmetric 4f shell with respect to the direction of the resulting magnetic moment of 4f electrons.
