Computational Study of Magnetic Properties of L10 Ordered Feni and Fept Binary Alloys
A Monte Carlo simulation has been used to explore the magnetic properties of L10 ordered FeNi and FePt binary alloys. Our Hamiltonians include Heisenberg interaction or Ising interaction. Our calculations of variations of specific heat [[EQUATION]] , magnetic susceptibility χ and the magnetization [[EQUATION]] with the temperature [[EQUATION]] showed that predicted critical temperature for ferromagnetic phase is very close to the experimental values for these alloys. Also, thermal hysteresis loops, magnetic remanence, and the coercive field have been calculated. Moreover, the magnetic properties of the ferrimagnetic phase are presented
