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 −⌬S M and adiabatic temperature change ⌬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 −⌬S M ͑10.9 J kg −1 K −1 ͒ and ⌬T ad ͑3.6 K͒ 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.
