| Abstract | Polycrystalline GdGa compound was prepared by arc-melting method. X-ray powder diffraction reveals that GdGa crystallizes in the CrB-type structure. The Curie temperature of the compound is 183 K. A distinct peak associated with spin reorientation transition was shown around 100 K on the magnetization versus temperature Curve measured in a field of 0.05T. Isothermal magnetic entropy change (vertical bar Delta S(M)vertical bar) was estimated based on the magnetization isotherms. The maximum value of vertical bar Delta S(M)vertical bar is 4.81 J kg(-1) K(-1) under the apphed field changing from 0T to 5.0 T. The relative cooling power (RCP(S)) of GdGa compound is about 576 J kg(-1) under an applied field change of 5 T. The specific heat of the compound has been estimated within the framework of Debye and mean field approximations to evaluate the adiabatic temperature change (Delta T(ad)). (C) 2008 Elsevier B.V.
