中文摘要	Large reversible magnetocaloric effect, which is associated with a second-order magnetic transition at 28 K, has been observed in DyCuAl compound. The maximum values of magnetic entropy change -Delta S(M) and adiabatic temperature change Delta T(ad) are 20.4 J kg(-1) K(-1) and 7.7 K for a field change of 0-5 T, respectively. Especially, the large values of -Delta S(M) (10.9 J kg(-1) K(-1)) and Delta T(ad) (3.6 K) with a considerable refrigerant capacity value of 150 J kg(-1) are also obtained for a relatively low field change of 0-2 T, suggesting that DyCuAl compound could be considered as a good candidate for low-temperature magnetic refrigerant.
