| 中文摘要 | We investigate magnetic properties and magnetocaloric effects of R2CoGa3 (R = Gd, Dy, and Ho) compounds. It is found that all the compounds are ferromagnetic with the Curie temperatures of T-C = 50, 17, and 10K for R = Gd, Dy, and Ho, respectively. The R2CoGa3 have large magnetic entropy change (Delta S) that arise from the second-order ferromagnetic-to-paramagnetic phase transition. The maximum values of Delta S are found to be -12.6, -10.8, and -13.8 J/kg K with corresponding refrigerant capacity values of 382, 252, and 287 J/kg for a magnetic field change of 0-50 kOe, respectively. The large Delta S values with little or no hysteresis losses as well as wide working temperature spans imply that the R2CoGa3 compounds may serve as promising candidates for magnetic refrigeration.
