Monte Carlo study of a mixed spin (1, 3/2) ferrimagnetic nanowire with core/shell morphology

In this work, Monte Carlo simulation based on Metropolis algorithm was used to study the magnetic behavior of a ferrimagnetic nanowire on a hexagonal lattice with a spin-3/2 core surrounded by a spin-1 shell layer with antiferromagnetic interface coupling in the presence of the crystal field interactions. The influences of the crystal field interactions, the interfacial and core couplings on the critical and compensation behaviors of the nanowire, are investigated. The results present rich critical behavior, which includes the first-and second-order phase transitions, the tricritical and critical end points. In addition, the compensation points can appear for appropriate values of the system parameters.
