Investigation of Magnetocaloric Properties in the TbCo<sub>2</sub>-H System
In this work the magnetocaloric effect in the TbCo<sub>2</sub>-H system in the region of the Curie temperature was studied both by direct and indirect methods in external magnetic fields up to ~1.4 and 14 T, respectively. We have paid special attention to the magnetic and magnetothermal...

| description | In this work the magnetocaloric effect in the TbCo<sub>2</sub>-H system in the region of the Curie temperature was studied both by direct and indirect methods in external magnetic fields up to ~1.4 and 14 T, respectively. We have paid special attention to the magnetic and magnetothermal properties of the TbCo<sub>2</sub>–H with high hydrogen content. The mechanisms responsible for the change in the Curie temperature were established, and the field and temperature dependences of the magnetocaloric effect were analyzed in detail. In addition, the magnetocaloric properties (including critical parameters) for various systems based on the TbCo<sub>2</sub> compound were compared. The main regularities of the change in the MCE value and the Curie temperature depending on the composition are discovered and discussed. |
