Magnetization spin reorientation and crystalline electric field coefficients of RCo"5 (R = Pr, Nd, Tb, Dy and Ho) compounds - Huai-Shan, L.; Rui-Wang, J. (Elsevier)
By means of the single-ion crystalline electric field (CEF) model we have investigated the spin reorientation of RCo"5 (R = Pr, Nd, Tb, Dy and Ho) compounds and discussed the contributions of high order CEF terms B^0"4 and B^0"6 to magnetocrystalline anisotropy. In addition, viewof the anisotropic competition of sublattice R and Co, we have fitted the temperature dependence of the easy cone angle θ, which is the angle between the easy direction of the magnetization and the c-axis. The CEF coefficients B^m"n are obtained by fitting the experimental data. The variations of the total free energy F"t"o"t for each RCo"5 compound changing with angle θ are presented.
