Abstract
We present the magnetocaloric properties of the substituted Heusler alloy Ni2Mn1−xCuxGa, which shows a maximum magnetic entropy change of ΔSM ≈ −64 J/Kg K = −532 mJ/cm3 K at 308 K for a magnetic field change ΔH = 5 T. The dependence of ΔSM on ΔH is approximately linear and does not reach saturation at 5 T. It is demonstrated that the temperature at which ΔSM occurs can be tuned through subtle variations in composition.
