Abstract
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.
