多晶Ni 2。18m0。采用差示扫描量热法、磁性和电阻率测量方法研究了具有耦合磁结构转变的8 2 Ga Heusler合金。磁子系统和结构子系统的耦合导致合金具有不同寻常的磁性特征。Ni 2的这些不寻常的磁性。18m0。82ga是由四方铁磁相到立方顺磁相的一阶结构转变引起的。
Polycrystalline Ni 2 . 1 8 Mn 0 . 8 2 Ga Heusler alloys with a coupled magnetostructural transition are studied by differential scanning calorimetry, magnetic and resistivity measurements. Coupling of the magnetic and structural subsystems results in unusual magnetic features of the alloy. These uncommon magnetic properties of Ni 2 . 1 8 Mn 0 . 8 2 Ga are attributed to the first-order structural transition from a tetragonal ferromagnetic to a cubic paramagnetic phase.
