在能带模型的基础上，利用由低温比热和饱和磁化强度实验数据确定的态密度曲线，估算了铁磁性金属铁及其含钴、镍、铬、钒合金在0°K下的高场磁化率。对于铁钴和铁镍合金，磁化率的浓度依赖性的计算结果和观测结果之间获得了令人满意的协议。利用无相互作用的自由自旋波模型计算了磁化率随温度和磁场的变化关系。计算结果解释了所观察到的磁化率的温度依赖性。
On the basis of the band model, high field susceptibilities for ferromagnetic iron metal and its alloys with cobalt, nickel, chromium and vanadium are estimated at 0°K, by making use of the density of states curve, determined from the experimental data of the low temperature specific heat and saturation magnetization. A satisfactory agreement between the calculated and observed results on the concentration dependences of the susceptibility is obtained for iron-cobalt and iron-nickel alloys. The dependences on temperature and magnetic field of the susceptibility are calculated by the model of non-interacting free spin waves. The observed temperature dependence of the susceptibility is explained by the calculated result.
