An investigation of competition on the dynamic magnetic properties of the core/shell nanowire

Abstract

In this study, we investigate the dynamic magnetic properties of Ising-type core/shell nanowires (NW) for different spin systems. The model of NW X(Spin-1/2)@Y with Y = Spin-1/2, Spin-1 and Spin-3/2 are considered for discussing an effect of the nature of shell particle on the dynamic properties. The mean-field theory and Glauber-type stochastic dynamics have been successfully applied to this, and the results of the dynamic magnetic properties for the core/shell NW are obtained. Different shell spin states are employed to the analysis of dynamic magnetic behavior for core/shell NW. Results of numerical calculation for the magnetization and coercivity curves are discussed for the effect of shell particles, shell interaction and oscillating field frequency. All results present that dynamic magnetic properties of the NW strongly dependent on the shell particle and the shell interaction.
