Dynamic magnetic behaviors in the Ising-type nanowire with core-shell single-ion anisotropies under a time-dependent oscillating external magnetic field

摘要

Highlights?The kinetic of a spin-1 Ising system on hexagonal nanowire are studied.?The effective-field theory and the Glauber-type stochastic dynamics are used.?The effects of the Hamiltonian parameters on the system are examined.?The behavior of dynamic core, shell and total magnetizations are analyzed.?The dynamic phase diagrams in the different planes are presented.AbstractIn the present study, the Ising-type nanowire with core-shell single-ion?anisotropies is studied to investigate the dynamic magnetic behaviors such as the dynamic magnetizations, hysteresis loop areas and dynamic correlations. Thermal and parametric dependences of them are obtained by utilize the effective-field theory with correlations and the Glauber-type stochastic dynamics approach. Thanks to, the nature (first-or second-order) of the dynamic transitions are characterized and the dynamic phase transition temperatures are determined. The effect of interaction parameters on the dynamic phase diagrams is also studied.]]>
