Dynamic magnetic properties in the kinetic Ising ferromagnet on triangular lattice within the effective-field theory and using Glauber-type stochastic dynamics

摘要

Dynamic magnetic properties in the kinetic Ising ferromagnet on a triangular lattice are studied within the effective-field theory with correlations and using Glauber-type stochastic dynamics. In particular, we investigate the time variations of average order parameters and thermal behaviors of the dynamic total magnetizations and present the dynamic phase diagrams. The tricritical point, the triple point and zero critical end point as well as reentrant behaviors are found in the dynamic phase diagrams. We also study the dynamic hysteresis behaviors of the system. When the hysteresis behaviors of the system are examined, single hysteresis loop as well as S-shaped thin loops and elliptical shapes are observed for various values of the physical parameters. Results are compared with some other dynamic studies and quantitatively good agreement is found. (C) 2015 Elsevier B.V. All rights reserved.
