Magnetic behavior of a cylindrical ferrimagnetic nanotube with spin-3/2 core and spin-3 shell

Abstract

The effects of exchange interactions and crystal fields on the critical and magnetic behaviors of a mixed-spin cylindrical ferrimagnetic nanotube with spin-$3/2$ core and spin-3 shell were studied using the mean-field approximation based on the Gibbs-Bogoliubov inequality. Typical magnetization curves and phase diagrams were established to explore various critical behaviors, including second and first-order phase transitions, compensation temperatures, and critical end-points. These characteristics and others are crucial for industrial applications of these systems.
