研究了多晶合金Ni2.19Mn0.81Ga从立方顺磁到四方铁磁的一级磁结构相变的磁性能。在20 ~ 100kOe的磁场范围内，观察到等温磁化M(H)在磁结构转变温度区间内的滞回行为。在磁场H=400和60kOe时测量的磁化强度M的温度依赖性表明，磁结构转变温度随磁场的增加而升高。
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 100kOe. Temperature dependencies of magnetization M, measured in magnetic fields H=400 and 60kOe, indicate that the temperature of the magnetostructural transition increases with increasing magnetic field.
