Systematic doping by transition elements Fe, Co and Ni on each site of Ni2MnGa alloy reveal that in bulk material the increase martensitic transformation temperature is usually accompanied decrease ferromagnetic Curie temperature, vice versa. The highest (571 K) was found for Ni50.0Mn25.4(Ga20.3Ni4.3) with result a reduction 55 K. point (444 (Ni44.9Co5.1)Mn25.1Ga24.9; however, reduced to 77 dep...
