Abstract
Atomic migration energies of 0.91Â eV, 0.66Â eV and 0.74Â eV have been deduced in FePd from the phonon density of state in the L10 phase at 300Â K and 860Â K, and in the face-centered cubic phase at 1020Â K, respectively. A good agreement is observed with the resistivity measurement results. Effective pair interactions have been determined using both an inverse cluster variation and an inverse Monte Carlo method. The results of the two methods agree well and lead to the predominance of the second effective pair interaction V2. The relevance of the deduced pair interactions is tested in terms of order-order and order-disorder kinetics simulations using a Monte Carlo model.
