Static and dynamic magnetic behaviors of two trimer-decorated graphene-like nanoparticles

Abstract

Abstract The mixed spin-5/2 and 1 Ising model is presented for describing two trimer-decorated graphene-like nanoparticles. The magnetic behaviors of the two models are studied using an effective field theory with correlations. Some features are found when the typical parameters, such as, simultaneous transverse magnetic field and anisotropy are considered. The possibility of stable and unstable magnetizations are judged by the lowest energy principle. The compensation and multiple phase temperatures for the magnetization curves depend on various physical parameters. The dynamic magnetic behavior of the system is reported in the periodically oscillating magnetic field.
