摘要

采用基于Gibbs-Bogoliubov不等式的平均场近似，研究了交换相互作用和晶体场对具有自旋-3/2核和自旋-3壳的混合自旋圆柱形铁磁纳米管临界行为和磁性行为的影响。建立了典型的磁化曲线和相图，以探索各种临界行为，包括二阶和一级相变、补偿温度和临界终点。这些特性和其他特性对于这些系统的工业应用至关重要。

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

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.
