"Domain Wall Formation in Ni_xFe_1-x";
Physical Review Letters, 98 (2007), 0272051 - 0272054.

In terms of a multiscale approach based on the Landau-Ginzburg expansion and on ab initio parameters
evaluated by means of the fully relativistic screened Korringa-Kohn-Rostoker method, the width of
domain walls is evaluated for the whole range of concentration in NixFe1 x. It is found that domain-wall
formation occurs only for x< 20% and x> 55%; i.e., in the neighborhood of the structural phase
transition from bcc to fcc, NixFe1-x first tends to form single domains before the actual range of
concentrations of this phase transition is reached. The calculated domain-wall widths are found to be in
reasonably good agreement with available experimental data.
