Magnetocaloric effect has been studied for antiferromagnetic single crystalline DySb, by measuring the temperature (T) and magnetic field (H) dependences of magnetization in the range 2≤T≤300K and 0≤H≤7T with field along the [100] and the [110] direction. The magnetic entropy change caused by a field change of 5 T is as larger as -36.4 J kg-1 K -1 for H//[110] around 11 K, which is a value much greater than that reported for the polycrystalline sample. The magnetocaloric effect is further found to be anisotropic. Above TN (=10 K), the entropy change is much larger for H//[110] than for H//[100]. In contrast, the entropy change is positive below TN, and it is significantly lower for H//[110] than for H//[100]. Our results indicate that DySb is a typical material possessing giant and highly anisotropic magnetocaloric effect, and suggest that magnetic orientation could be used to enhance magnetic entropy change.
