Dilution effect on the compensation temperature in a honeycomb nano-lattice: Monte Carlo study

In this work, we use Monte Carlo simulations with the Metropolis algorithm to study the dilution effect on the magnetic properties in a honeycomb nano-lattice. The geometry of the system is formed by two sub-lattices of 45+45 = 90 atoms consisting of the spins σ = 3/2 and S = 5/2. The ground state phase diagrams at zero absolute temperature are presented. Also, the variation of the total magnetization with reduced temperature for several values of the reduced exchange coupling are discussed. It is found that the compensation temperature depends on the reduced exchange coupling parameters. Furthermore, the dilution of the S spins affects the compensation temperature and hysteresis loops of the studied system.
