在f.c.c.上进行热膨胀测量。Fe 65（Ni 1-xMnx）35合金在温度低至4.2°K时的自发体积磁致伸缩，并由它们的热膨胀曲线估算了这些合金的自发体积磁致伸缩。结果表明，铁磁合金（x <0.3）在0°K时的自发体积磁致伸缩为正值，随x的增大而减小;反铁磁合金（0.3< x）在0 ° K时的自发体积磁致伸缩为正值，随x的增大而增大。自发体积磁致伸缩随温度的变化为T2的温度范围内低于约一半的磁转变温度。如果假设一个简单合理的态密度曲线，这些实验结果可以从弱巡游电子铁磁性或弱巡游电子反铁磁性的角度来理解。
Thermal expansion measurements were made on f.c.c. Fe 65 (Ni 1- x Mn x ) 35 alloys at temperatures down to 4.2°K and the spontaneous volume magnetostriction of these alloys was evaluated from their thermal expansion curves. The results indicate that the spontaneous volume magnetostriction at 0°K is positive and decreases with increasing x in the ferromagnetic alloys ( x <0.3), and is positive and increases with increasing x in the antiferromagnetic alloys (0.3< x ). The spontaneous volume magnetostriction varies with temperature as T 2 in the temperature range below about half of the magnetic transition temperature. If a simple and reasonable density of states curve is assumed, these experimental results can be understood on the basis of the weak itinerant electron ferromagnetism or of the weak itinerant electron antiferromagnetism.
