Abstract

Self- and heterodiffusion data in alpha-Fe, in ferromagnetic and paramagnetic slate are analysed taking into account the anharmonic properties of the bulk material. The values obtained for the activation enthalpy, entropy and Gibbs energy are in agreement with the experimental values, given by Ceise & Herzing (1987) and Cermak et al. (1989). Using the elastic data of alpha-Fe, we calculate the lambda parameter which in its definition contains the exchange integral for an atom at the saddle point and the equilibrium position. Furthermore, the influence of spin ordering in the activation Gibbs energy, in the Curie temperature zone, is investigated.
