Magnetic properties of a polycrystalline alloy Ni2.19Mn0.81Ga, which undergoes a first-order magnetostructural phase transition from cubic paramagnetic to tetragonal ferromagnetic phase, are studied. Hysteretic behavior of isothermal magnetization M(H) has been observed in a temperature interval of the magnetostructural transition in magnetic fields from 20 to 100 kOe. Temperature dependencies of magnetization M, measured in magnetic fields H = 400 and 60 kOe, indicate that the temperature of the magnetostructural transition increases with increasing magnetic field.
