Abstract
The influence of the degree of atomic order on the electrical and magnetic properties of Fe-Si alloys with different Si-contents was determined. Five different Fe-Si alloys with Si-contents ranging from 6-14 at%Si were annealed from 500 to 1100°C for 2 h and then quenched in water in order to develop different degrees of order. 57Fe Mossbauer spectra were obtained in order to determine the type and degree of order. Differential scanning calorimetry was performed to detect the disorder/order transition. The disordering in the samples greatly increase the electrical resistivity. Moreover, losses increase with annealing temperature due to the generation of internal stresses and/or creation of disordering.
