Abstract

The magnetization process of in-plane anisotropy system with tetragonal structure has been examined on the basis of rigid coupled magnetization and two sublattice magnetization models. By applying graphical and fitting methods, the magnetocrystalline anisotropy constant sets for Er₂Fe₁₄B and Tm₂Fe₁₄B at 4.2K have been determined as K_1Er = - 1255J/kg, K_3Er = - 30J/kg, N_ErFc = 0.43 T/Am² kg^-1 and K_1Tm = - 6830J/kg, K_3Tm = - 260J/kg, N_TmFe = 0.38 T/Am² kg^-1, respectively. The magnetizations calculated by energy minimum method by applying the anisotropy constant sets reproduced well the experiments and satisfied the simulation assumptions.
