TL;DR

This paper studies how random dilution of single-ion anisotropy affects the phase behavior of a kinetic Blume-Capel model under oscillating magnetic fields using Glauber dynamics, revealing diverse phase diagrams.

Contribution

It introduces a kinetic Blume-Capel model with random dilution of anisotropy and analyzes its phase diagrams under oscillating fields, extending understanding of disordered spin systems.

Findings

Fourteen distinct phase diagrams observed with varying anisotropy concentration.

Comparison shows differences between diluted and pure spin-1 Ising systems.

Dilution significantly influences phase transition characteristics.

Abstract

This investigation employs a square lattice and Glauber dynamics methodology to probe the effects of diluteness in the crystal-field interaction in a Blume-Capel Ising system under an oscillating magnetic-field. Fourteen different phase diagrams have been observed in temperature-magnetic-field space as the concentration of the crystal-field interactions is varied. Besides, a comparison is given with the results of the pure spin-1 Ising systems.
