通过磁化强度测量系统地研究了Ni 50 Mn 50 −xInx/2 Sbx/2 Heusler合金奥氏体相中磁性能的浓度依赖性。Ni 50 Mn 50 −xInx/2Sbx/2合金的居里温度几乎与含量x无关。另一方面，浓度对磁矩的依赖性显示出与具有相同价电子数的Ni 50 Mn 50 −xSnx合金相似的凹形曲线。这种趋势表明，磁矩继续增加，降低含量x，并达到亚稳铁磁NiMn-B2相。
The concentration dependence of magnetic properties in the austenite phase of Ni50Mn50−xInx/2 Sbx/2 Heusler alloys was systematically investigated by magnetization measurements. The Curie temperature for Ni50Mn50−xInx/2Sbx/2 alloys is almost independent of content x. On the other hand, the concentration dependence on magnetic moment shows a concave curve similar to that of Ni50Mn50−xSnx alloys, which have the same number of valence electrons. This tendency suggests that the magnetic moment continues to increase with decreasing content x and reaches that of the metastable ferromagnetic NiMn-B2 phase.
