| 英文摘要 | Pyrochlore RE2TiMnO7 (RE = Dy and Ho) compounds were synthesized using a ceramic method, and their crystal structures, microstructures, and cryogenic magnetic properties were determined. Dy2TiMnO7 and Ho2TiMnO7 compounds belong to the Fd-3m space group with a cubic pyrochlore structure and show a considerable reversible magnetocaloric effect (MCE) in the vicinity of the second-order ferromagnetic-paramagnetic (FM-PM) phase transition at the Curie temperature (TC) of 7.6 and 7.5 K, respectively. The obtained maximal values of magnetic entropy change (-ΔSMmax) for Dy2TiMnO7 and Ho2TiMnO7 are 12.50 and 13.95 J/kg K under a magnetic field change (ΔH) of 0–7 T, respectively. Correspondingly, the relative cooling power (RCP) values reach 530.3 and 573.2 J/kg, respectively. © 2018 Elsevier Ltd and Techna Group S.r.l. |
