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 K1Er = - 1255J/kg, K3Er = - 30J/kg, NErFc = 0.43 T/Am2 kg-1 and K1Tm = - 6830J/kg, K3Tm = - 260J/kg, NTmFe = 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.
