- Аннотация: A complex study of structure, phase composition, surface topology, magnetic, and magnetocaloric properties was performed for TbCo2 and Tb0.3Dy0.7Co2 compounds and for a Tb0.3Dy0.7Co2H0.5 hydride with a low hydrogen content. The hydrogenation was established to impact the structural features at the microand nanolevels, as well as the fundamental and functional properties. Introducing even a small amount of hydrogen in the crystal lattice of Tb0.3Dy0.7Co2 compound is found to cause an increase in both the Curie temperature and the magnetic moment at the cobalt atoms. The magnetic phase transition from the paramagnetic to the magnetically ordered state changes from the first (in Tb0.3Dy0.7Co2) to the second (in TbCo2 and Tb0.3Dy0.7Co2H0.5) order, leading to a noticeable decrease in the magnetocaloric effect.
