Hysteresis and compensation behaviors of mixed spin-2 and spin-1 hexagonal Ising nanowire core–shell structure

•Critical temperature increase when exchange interaction increasing in core-shell.•Hysteresis loop areas decrease at above transition temperature.•Magnetic coercive field decrease when crystal field increasing.•Magnetic coercive field increase when exchange interaction increasing.

The magnetic behaviors of a mixed spins (2-1) hexagonal Ising nanowire with core–shell structure are investigated by using the Monte Carlo simulations. The thermal magnetizations, the magnetic susceptibilities and the transition temperatures of core–shell are studied for different values of crystal field and exchange interactions. The thermal and magnetic hysteresis cycles are given for different values of the crystal field.
