Abstract

The compound Tm2Fe17, the only one among R2Fe17 (where R is a rare earth metal), exhibits uniaxial magnetic anisotropy at cryogenic temperatures. Its Curie temperature is close to room temperature, T C = 295 K. Magnetic phase diagrams for the Tm2Fe17–H system have been constructed on the basis of measuring the temperature and field dependences of magnetization performed for different crystallographic directions of single-crystalline samples of Tm2Fe17 and its hydrides Tm2Fe17Hx (x = 1, 2, 3, 4). It has been found that the hydrogen atoms, located in the interstices of the crystal lattice of this compound, have a significant effect on both its Curie temperature and the type of magnetic anisotropy.
