摘要

This work presents a computational modeling and investigation of the magnetic properties of Fe-Ni alloys, using Monte Carlo simulation (MCS).The study explores the effect of substitutional doping in the Fe1 − xNix system, with the nickel concentration x varying from 0.1 to 0.9. The simulations are conducted within the framework of the Ising model to analyze how replacing Fe atoms with Ni influences the alloy’s magnetic behavior. The internal energy has been studied alongside the magnetization, the magnetic susceptibility, and the specific heat. Moreover, magnetic hysteresis loops have been investigated at various temperatures. In addition, the Curie temperature (TC) has been determined for each composition; an increase in TC was observed by increasing the percentage of Ni substitution. For 80% nickel, we established that the simulation results of Permalloy Fe20-Ni80 ( \(\:{T}_{C}=851\:K)\:\) coincide with experimental results ( \(\:{T}_{c}^{exp}\cong\:858\:K)\) . Furthermore, our results show that the greatest Curie temperature has been found for 90% nickel. Hence, the Monte Carlo method employed with Ising model allowed for the computation of these magnetic properties. Besides, the composition significantly affects the Curie temperature in Fe-Ni alloys. Therefore, temperature strongly influences the Hysteresis loop of Fe-Ni alloys. The results provide valuable insights into the relationship between composition and magnetic properties in Fe–Ni alloys, contributing to the understanding and optimization of these metallic materials for technological applications.
