利用递推方法在紧束缚d带模型中计算了Y-Co（Y2Co17、YCo5、Y2Co7和YCo3）、Y-Fe（Y2Fe17、Y6Fe23和YFe3）和Y6Mn23金属间化合物的电子态密度。计算了Co和Fe原子的平均磁矩、局部磁矩、高场磁化率和低温比热系数，并与实验值进行了比较。还计算了 Y-Fe 化合物中自旋磁化率和自发体积磁致伸缩的温度依赖性，并与实验结果进行了比较。
Electronic densities of states in Y-Co (Y2Co17, YCo5, Y2Co7 and YCo3), Y-Fe (Y2Fe17, Y6Fe23 and YFe3) and Y6Mn23 intermetallic compounds are calculated in the tight-binding d-band model by making use of the recursion method. The average and local magnetic moments on Co and Fe atoms, the high-field susceptibility and the coefficient of the low-temperature specific heat are calculated and compared with the experimental values. The temperature dependences of the spin susceptibility and the spontaneous volume magnetostriction in Y-Fe compounds are also calculated and compared with the experimental results.
