| Abstract: | On the basis of the single\|ion model, a method of calculation on the magnetization curves for magnetically aligned rare\|earth\|Fe(Co) intermetallic compound is developed. High\|field magnetization curves for magnetically aligned Nd\-2Fe\-\{14\}B and Pr\-2Fe\-\{14\}B were calculated by using the above method. In the calculations, the fitted exchange and crystalline field parameters from magnetization curves of the single crystals were used. The calculated curves agree well with the experiments. |
