Abstract

Simulations of Fe1-xCox alloys as thin films using Monte Carlo Method and Heisenberg model have been carried out. Changes in magnetic properties, transition temperature, and coercive field as a function of the cobalt concentration (x) were observed. Semi-periodic conditions were used for the samples construction. A Hamiltonian expression which contains terms corresponding to the nearest neighbors interaction and the Zeeman effect was used. Three types of exchange parameters were considered: Fe-Fe, Fe-Co y Co-Co. Furthermore, cobalt atoms were randomly placed inside the BCC crystal lattice of Fe. Decrease not only in the critical temperature but also in the coercive field was observes as the concentration x was increased.
