Impact of geometry on magnetic behavior in rectangular, square, diamond, and triangular graphene nanostructures: A Monte Carlo study

Abstract

This study explores the impact of shape and form and interaction parameters on the magnetic behavior of graphene nanostructures using Monte Carlo simulations. It examines the roles of exchange coupling J, biquadratic coupling K, external magnetic field H, and crystalline field D in influencing the blocking temperature T_B. The study highlights the interplay between these parameters and the geometric variations of the nanostructures, providing insights for optimizing materials in spintronics and data storage applications.
