Abstract

The structural and magnetic properties of Fe7jsSii35B9Cui(Ta/Nb)j alloy ribbons after heat treated carried out (by using a conventional furnace and the Joule heating method) at temperatures and current densities when a partial devitrification to a nanocrystalline structure occurs have been studied. Room temperature magnetization work (Wm) and coercivity (Hc) were evaluated for several nanocrystalline samples having different grain size (D). Variations of Wm with the thermal treatment parameters are interpreted in the framework random anisotropy model in terms of the relaxation processes as well as in those pinning centres according to the annealing conditions and the nature of the nanocrystallization process. From our experimental results of HC(D) it was found a DM law which could be explained by extending the original random anisotropy model.
