- Аннотация: We present a study of the hydrogenation effect on structural and magnetic properties of HoFe11Ti single crystal. Single crystal hydride HoFe11TiH x with H concentration x = 1 at. H/f.u. has been prepared. Magnetization measurements along the main symmetry directions of the tetragonal structure have been performed on HoFe11TiHx (x = 0,1) single crystals at applied high magnetic fields up to 80 kOe in the temperature range from 4.2 to 300 K. Torque measurements were carried out in the temperature range 78-700 K in magnetic fields up to 13 kOe. The single-ion magnetic exchange and crystalline-electric-field interaction model has been applied to the fitting of the experimental behavior of the single-crystal HoFe11TiHx (x = 0,1) samples. A set of CEF parameters and mean exchange field has been obtained. Hydrogen atoms have been found to have a significant effect on the second-order crystal field parameter A 2 0 (A 2 0 = -20.5 Ka 0 -2 for HoFe11Ti and A 2 0 = -118 Ka 0 -2 for HoFe11TiH).
