本文用穆斯堡尔谱学分析了Fe-Ni因瓦合金的磁结构特征,讨论了因瓦机理以及掺加稀土Pr对合金结构、性能的影响。实验表明:Fe-Ni因瓦合金的内磁场分布曲线呈双峰特征,表明合金中共存有铁磁性和反铁磁性两种
In this paper, the magnetic structure of Fe-Ni Invar alloy was analyzed by Mossbauer spectroscopy. The influence of Invar mechanism and the addition of rare earth Pr on the structure and properties of the alloy was discussed. The experimental results show that the internal magnetic field distribution curve of Fe-Ni Invar has a bimodal characteristic, indicating that there are two kinds of ferromagnetic and anti-ferromagnetic alloys
