基于外斯的唯象理论,导出了添加元素提高热敏磁性合金Bm-T曲线陡度所应满足的必要条件:(ISB(O))/(ISA(O))(TCA/TCB)~(1/2) >1。根据添加元素使合金的居里温度和饱和磁化强度变化的各种效应,可将它们分成六种类型。应用这种分类方法分析了面心立方结构范围内的铁-镍合金。结果指出铁在此范围内显示出四种不同的磁性效应。本研究还指出:锰加入镍-铜系中提高三元合金Bm-T曲线的陡度;并且铜和锰对镍的磁性的影响具有各自原来的效应。
Based on the alien’s phenomenological theory, the necessary conditions for adding the elements to improve the steepness of the Bm-T curve are derived: (ISB (O)) / (ISA (O)) (TCA / TCB) 1/2)> 1. Depending on the effects of adding elements to the various effects of varying the Curie temperature and the saturation magnetization of the alloy, they can be divided into six types. This classification method is used to analyze the iron-nickel alloy in the face-centered cubic structure. The results indicate that iron shows four different magnetic effects in this range. The study also points out that the addition of manganese to the nickel-copper system increases the steepness of the Bm-T curve of the ternary alloy, and the effect of copper and manganese on the magnetism of nickel has its own original effect.
