Abstract

In this paper, we investigated the effect of vacant sites on the magnetic properties of the germanene nanostructure. The Blume-Capel model was utilized to investigate the nano-system with the spin-7/2. Moreover, we employed Monte Carlo simulations (MCS) with the Metropolis algorithm to explore how the presence of vacant sites influences the magnetic properties under varying parameters such as temperature, exchange coupling interaction, crystal field, and external magnetic fields. It has been found that the transition from the ferromagnetic phase to the superparamagnetic one takes place more quickly by increasing the value of the vacancy number (VN). Besides, increasing the parameter VN leads to a decrease in the remanent magnetization while the coercive field remains constant. These findings can improve the examined system for potential nanotechnology applications.
