Motivated by spintronic devices and their applications, we engineer a model to investigate the magnetic properties of nano-alloy Fe[Formula: see text]Co[Formula: text]. Where [Formula: text] is fraction iron atoms Fe substituted cobalt Co atoms, corresponds 50% this compound then called equiatomic FeCo. The purpose work apply Monte-Carlo Simulations (MCS), under Metropolis algorithm predict such system. In first step, propose describing system including different exchange coupling interactions. Then, establish analyze ground state phase diagrams, in planes. For non-null temperature values, applied MCS algorithm. behavior both magnetizations susceptibilities are illustrated as function temperature. Also effect interactions studied discussed. hysteresis loops presented analyzed for specific values temperature, concentrations.
