The temperature dependence of electrical resistivity of a-Fe100-xZrx alloys (x = 8.5 and 9.5) is measured in the temperature range 5 to 300 K. Our observations indicate some correlations between the magnetic and electrical resistivity behavior near the transition region. The resistivity data have been analyzed in the light of both magnetic and nonmagnetic scattering models to quantify the contributions from these scattering processes. From the quantitative analysis it is found that the magnetic contribution is noticeable around the transition temperature and the nonmagnetic contribution is present in the complete temperature range of the present study.
