| Abstract: | The electrical resistivity of amorphous (Fe1-xZrx)84.5B15.5 (X=0, 0.02, 0.04, 0.06, 0.08, 0.1 and 0.15) and Fe90-xBxZr10 (X = 0, 4, 10, 16 and 20) alloys has been studied as a functiom of temperature in the range of 300 to ≈950 K. We find that, for the samples with X = 0.02 to X = 0.08, the curves of ρ(T)/ρ(300 K) vs T have two linear slopes and the turning point appears above curie temperature Tc. The temperature coefficients α1 of the electrical resistivity at Tc decrease with the increase of Zr content. Above 8 at% Zr, ρ(T)/ρ(300 K)-T curves of the all samples show negative temperature coefficients and a minimum near Tc. Finally, the composition dependence of the minimum temperature Tmin and the temperature coefficients α of resistivity are discussed in brief. |
