Abstract
In this research, the mixed-spin (3/2, 1) Ising model with a core–shell nanoparticle structure is constructed, and its magnetic properties are investigated by Monte Carlo method. Initially, the ground-state phase diagram of the system is analyzed. Secondly, the influence of Hamiltonian parameters including exchange coupling, crystal field, and external magnetic field and other physical parameters including temperature, size, and atomic concentration on the magnetic properties of the system is investigated. Under certain conditions, compensation behavior occurs in the system, and the magnetic susceptibility curve appears with double peaks. Lastly, the hysteresis behavior is analyzed, revealing the presence of multiple hysteresis loops.
