Abstract

The temperature dependence of the electrical resistivity of amorphous Co_80-xEr_xB₂₀ alloys with x = 0, 3.9, 7.5 and 8.6 prepared by melt spinning in pure argon atmosphere was studied. All amorphous alloys investigated here are found to exhibit a resistivity minimum at low temperature. The electrical resistivity exhibits logarithmic temperature dependence below the temperature of resistivity minimum T_min. In addition, the resistivity shows quadratic temperature behavior in the interval T_min < T< 77 K. At high temperature, the electrical resistivity was discussed by the extended Ziman theory. For the whole series of alloys, the composition dependence of the temperature coefficient of electrical resistivity a shows a change in structural short range occurring in the composition range 8-9 at%.

 alloys with x = 0, 3.9, 7.5 and 8.6 prepared by melt spinning in pure argon atmosphere was studied. All amorphous alloys investigated here are found to exhibit a resistivity minimum at low temperature. The electrical resistivity exhibits logarithmic temperature dependence below the temperature of resistivity minimum T<sub>min</sub>
. In addition, the resistivity shows quadratic temperature behavior in the interval T<sub>min</sub>
 < T< 77 K. At high temperature, the electrical resistivity was discussed by the extended Ziman theory. For the whole series of alloys, the composition dependence of the temperature coefficient of electrical resistivity a shows a change in structural short range occurring in the composition range 8-9 at%.</EA>
