The method of paramagnetic magnetization (М) calculations of bulk equiatomic НЕА based on atoms Cr, Cu, Fe, Ni and Co is proposed. The methodology is based on the Langevin theory for paramagnetic materials. Calculations М were carried out during induction В = 1 і 5 Т, that correspond to the fields of ordinary (М) or saturation magnetization (Мs ). In addition, for such fields, the parameter of the Langevin function (L(a)), satisfies the condition a1, which simplifies function to form L(a) . М and Мs have order 10-3 emu/cm3, but Мs approximately 5 times greater than М. The calculated data agree satisfactorily with the literature data obtained for NEAs based on Al, Cr, Cu, Fe, Ni, and Co in the bulk (calculated data) or film (experimental data) state. The proposed technique can be used for preliminary estimation of values М and Мs in the case of other multicomponent alloys. |
