Abstract

The effect of hydrogenation on the structure and magnetic properties of TbFe11– xCoxTi compounds with different cobalt content (x = 0, 3, 4, and 5) has been studied. An X-ray diffraction  phase analysis was carried out and the parameters of the crystal structure of hydrides were determined. It is shown that hydrogenation leads to an isotropic increase in the unit cell volume. The experimental field and temperature dependence of the magnetization of single crystals hydride are studied in magnetic fields up to 90 kOe in the temperature range 5–300 K. The constants of magnetocrystalline anisotropy are determined.
