Monte Carlo Investigation of the Critical Behavior of a Core–Shell Nanotube

Abstract

Monte Carlo simulation is employed to examine a ferrimagnetic Ising‐type hexagonal nanotube, featuring a spin‐ core embedded in a spin‐1 shell. The impacts of specific exchange interactions and the crystal field on the magnetization and phase diagrams of the system are analyzed and discussed. Under certain physical conditions, the nanotube exhibits first‐ and second‐order phase transitions and compensation temperatures. The characteristics highlighted are significant for the technological applications of these systems, such as magnetic storage devices, sensors, and drug delivery systems.
