| 中文摘要 | Magnetization of compound La(Fe0.98Co0.02)(11.7)Al-1.3 was measured carefully as functions of temperature and applied field around its Curie temperature of similar to 198 K. Magnetic entropy change \DeltaS\, allowing estimation of the magnetocaloric effect (MCE), was determined based on thermodynamic Maxwell's relation. The achieved magnitude of \Delta Si\ reaches 10.6 J kg(-1) K-1 under a field of 5 T. The considerable entropy change is believed to be due to the high magnetization and the sharp change in magnetization at T-C. It is found that the magnetic phase transition is completely reversible in temperature, indicating a nature of second-order phase transition. |
