In the present study, we examine by comparison the dynamic magnetic and hysteretic properties of nanostructures with different magnetic core/shell particles confined within a shape structure of the wire. The model of nanostructures with core=spin-1 and shell=spin-3/2, namely cylindrical, cubic and hexagonal nanowire, is proposed for studying the effect of the geometry of wire shape on the magnetic and hysteretic properties. The results were obtained by mean-field theory as well as Glauber-type stochastic dynamics, and focused the response to thermal and hysteretic behaviours of systems. All results display dynamic magnetic properties of the nanostructure strongly dependent on the geometry of wire shape. Moreover, temperature and crystal field are proposed as the important factors affecting the dynamic properties of wire systems.
