Abstract
Magnetic properties of a polycrystalline alloy NiMnGa, which undergoes a first-order magnetostructural phase transition from cubic paramagnetic to tetragonal ferromagnetic phase, are studied. Hysteretic behavior of isothermal magnetization has been observed in a temperature interval of the magnetostructural transition in magnetic fields from 20 to 100 kOe. Temperature dependencies of magnetization , measured in magnetic fields and 60 kOe, indicate that the temperature of the magnetostructural transition increases with increasing magnetic field.
