Abstract
The effects of the hydrogen and the nitrogen on the magnetic properties (the Curie temperatures, saturation magnetization and magnetic anisotropy) of RFe11Ti and R2Fe11 compounds are studied. Structural and magnetic investigations has been performed by means of X-ray diffraction, torque and pendulum magnetometer techniques and high-field magnetization measurements on single crystal RFe11TiH1-δ and the magnetically aligned powder samples RFe11TiNx, R2Fe17Hx and R2Fe17Nx. The hydrides and nitrides still retain the structure of their parent compounds, but the unit cell volumes are expanded. The Curie temperature are increased by both hydrogenation and nitrogenation. Magnetic phase diagram of RFe11TiH1-δ and RFe11TiN1-δ compounds have been obtained. The signs of the first constants of magnetic anisotropy of a rare earth sublattice are in agreement with the sign of the Stevens factor of rare earth ions. The effect of the hydrogen and nitrogen atoms on rareearth sublattice anisotropy have been found to be opposite.
