中文摘要	The magnetic properties and magnetic entropy change near Curie temperature T-C have been investigated for the Ce2Fe16Al compound with a rhombohedral Th2Zn17-type structure. The magnetic behaviour is found to obey the second-order phase transition laws near T-C which is 275.8K. The critical indices beta = 0.44 +/- 0.01, gamma = 1.30 +/- 0.01, delta = 3.83 +/- 0.01 are obtained by calculating the field- and temperature-dependences of magnetization. The critical indices satisfy the scaling law gamma = beta(delta - 1), but these values deviate the three-dimensional Heisenberg model. The maximum entropy change at T-C under a field of 2 T is 1.95J/kgK.
