【Abstract】 The low temperature resistivity, thermoelectric power, high temperature resistivity and structural relaxation of amorphous Fe90-xCuxZr10 alloys have been measured. The low temperature resistivity curves exhibit a minimum around the Tc, which can be explained by the coherent exchange scattering model. The themoeletric power of alloys is negative in the temperature range of 77-380K, which can be explained by Mott s-d scattering model. The temperature dependence of the high temperature resistivity, out of accord with Ziman thery, is considered as the result of phase separation. Reversible and irreversible structural relaxation may be related to CSRO and TSRO respectively.更多还原
