Abstract

We have investigated the magnetocaloric properties on the Ni₂Mn_1−xA_xGa Heusler alloys with partial substitution of Mn by A = Co (x = 0.10, 0.20, and 0.30) and Cu (x = 0.15 and 0.20) in the vicinity of the martensitic transition by measuring magnetization curves at magnetic field up to 20 kOe and in the temperature range of 250–300 K. The changes of the magnetic part of entropy dependence on magnetic field and temperature have been evaluated.
