中文摘要	The magnetic properties and magnetocaloric effects of the ErNi1-xCuxAl (x = 0.2, 0.5, 0.8) compounds have been studied. The sample with x = 0.2 is found to be antiferromagnetic below the Neel temperature of T-N = 4.6K, while the sample x = 0.5 is simply ferromagnetic with a Curie temperature of T-C = 5.8K. In contrast, the sample x = 0.8 exhibits a short-range magnetic order, as revealed by AC magnetic measurements, and the transition temperature is 5.5K. Large magnetic entropy change (Delta S) without hysteresis losses has been observed around the transition temperature for all the samples. The Delta S displays a peak between 4K and 10K, and the maximal values of Delta S are -22.6, -25.9, and -24.8 J/kg K for the field changes of 0-5T, corresponding to the compositions of x = 0.2, x = 0.5, and x = 0.8, respectively. The large Delta S value as well as no hysteresis loss indicate that ErNi1-xCuxAl can be alternative candidates for magnetic refrigerant working at low temperature (< 10 K).
