Abstract

The magnetic properties, magnetocaloric effect (MCE) and rotating magnetocaloric effect (RMCE) in NdGa single crystal were investigated. NdGa single crystal exhibits large magnetic anisotropy and a large MCE for magnetic field along c axis at T_C (Curie temperature) of 42 K with the maximum magnetic entropy change (-ΔS_M ^max) of 21.1 J/kg K (magnetic field change of 0–7 T). The rotating entropy change from the easy axis (c axis) to hard axis (b axis) (ΔS_R, _cb) or NdGa single crystal reaches 16.6 J/kg K for the magnetic field of 7 T. Particularly, the value of ΔS_R, _cb is as high as 10.1 J/kg K in a relative low magnetic field of 2 T. The large MCE and RMCE, especially under low magnetic field, indicated that the NdGa single crystal could be a promising candidate for practical magnetic refrigeration.
