Resumen:
We have taken conversion electrons Mössbauer spectra to FeMn alloys with 7.5, 10.5 and
13.7 wt.% Mn, that allowed us to obtain the relative fractions of the different iron environments in
the bcc structure. We compare these populations with those obtained from Monte Carlo simulations.
The magnetic interactions between FeFe, FeMn and MnMn atoms have been modeled using an
Ising-type Hamiltonian in a 3D bcc lattice with periodic boundary conditions. The simulations were
performed using a Metropolis algorithm to determine the jump probability of Mn atoms.
