Abstract: In this paper it was identified and determined the correlation between the stress intensity and electrical resistivity sensitivity coefficient k σ of the amorphous Fe 81B 13Si 4C 2 ribbon. Crystallization process in this alloy occurs in the temperature range from 500 °C to 540 °C. Therefore, efficient relaxation of amorphous structure was performed by annealing at 400 °C for 30 min. The annealed alloy has stable structure in temperature range from room temperature to 300 °C, exhibiting low temperature resistivity coefficient and linear dependence of resistivity upon stress. Based on experimentally obtained dependence of termoelectromotive force upon temperature and stress, we have proved that electron state density at Fermi level decreases with stress increase. This causes an increase in resistivity of the ribbon sample, and consequently results in the improvement of sensitivity coefficient k σ. © 2011 Elsevier B.V. All rights reserved.
