Magnetic Properties and Hysteresis Behavior of the Ferrimagnetic Hexagonal Nanotube with Core–Shell Structure

The magnetic properties and hysteresis behavior of a ferrimagnetic hexagonal Ising nanotube with a mixed spin 3/2 core and a spin 5/2 shell structure are investigated by using mean-field approximation (MFA). The influences of the crystal field, the shell coupling and the interface coupling on the critical and compensation temperatures are analyzed. The acquired results reveal the presence of both first-and second order transitions, as well as the compensation temperatures. Moreover, by using appropriate physical parameters, we identify the emergence of single, triple and multiple hysteresis loops. These results are in qualitative agreement with theoretical and experimental investigations.
