Effect of Temperature on Physical Properties for Nickel Oxide (NiO) by Using Ising Simulation Model
Abstract
The main objective of this work to investigate the effect of changing in a factor of temperature on physical properties such as the critical temperature (Tc), the magnetization per spin (M), the energy per spin (E), the magnetic susceptibility (χ), and the specific heat (Cv ) of NiO for a 6X6 square lattice in the absence of external magnetic field by using Ising simulation model. The simulation results showed that the magnetization per spin changed from a positive value to a negative value at critical temperature (Tc≈ 47.2679045 J/KB) this indicates that the material transited from Antiferromagnetic to diamagnetic state. Also, the ground state energy of NiO was determined to be -38.125 meV.
