Abstract

Abstract Magnetic properties and hysteresis behavior of a mixed-spin (2, 1/2) square nanowire with a core–shell structure are investigated within the framework of the anisotropic Ising model, under the influence of lattice anisotropy and an external magnetic field. The analysis is conducted using the mean-field approximation (MFA). Numerical results include phase diagrams and magnetization curves, revealing both second- and first-order phase transitions, isolated critical points, and compensation phenomena. Furthermore, for specific sets of physical parameters, the system exhibits multiple hysteresis loops with distinct step-like features and various shapes thus leading to multi-step spin-tranition.
