Compositional dependence of magnetic entropy change in Ni 2+xMn1-xGa Heusler alloys was investigated experimentally. The largest entropy change ΔS=20.7±1.5 J/Kkg in the magnetic field H=1.8 T was revealed in the Ni2.18Mn0.82Ga alloy at a magneto-structural phase transition temperature of Ts=333.2 K. Magnetic-field-induced structural phase transition was observed.
