Magnetic anisotropy in the hexagonal RET5 compounds

Abstract

Using the methods of classical statistical mechanics, the field dependence of magnetization curves is calculated at room temperature for SmCo 5 , PrCo 5 and YCo 5. In addition, we discuss the dependence of the magnetization vector on the direction of the magnetic field, along and perpendicular to the easy-axis. We correlate the orientation of the magnetization vector, relative to a specific crystallographic axis, to the angular coordinates of the most probable location in a probability landscape of these anisotropic magnetic systems.
