Hysteresis and compensation behaviors of spin-1 hexagonal Ising nanowire

Abstract

An effective-field theory with correlations has been used to study the hysteresis, susceptibility and compensation behaviors of the spin-1 hexagonal Ising nanowire (HIN) with core-shell structure. The effects of the temperature, crystal field, core-shell interfacial coupling and shell surface coupling are investigated on hysteresis and compensation behaviors, in detail. When the core-shell interfacial coupling is weak, the double and triple hysteresis loops can be seen in the system. The hysteresis loops have different coercive field points that the susceptibility make peak at these points. Moreover, we observed that the system displays the Q-, R-, S-, P-, N- and W-types of compensation behaviors according to Ne\'el classification nomenclature. Finally, the obtaining results are compared with some experimental and theoretical results and found a good agreement.
