Mossbauer Analysis of Crystallization In Joule-heated Fe80b20

A detailed analysis of Mossbauer resonance data has been performed on Fe80B20 ribbon strips submitted to fast thermal treatment in order to achieve different crystallization stages. The samples were submitted to de Joule heating for various values of applied current. The evolving crystalline fraction is studied by analyzing the contributions of different phases to the Mossbauer spectra. The evolution of the mean hyperfine field of the remaining non-crystalline phase is followed through a similar analysis
