摘　　要： 对非晶态Fe_9(1-x)Cu_xZr_10(x=0,4,6,8,10,15,20)合金的低温电阻率、热电势率、高温电阻率和循环退火过程中的电阻率进行测量,结果表明:样品低温电阻率在T_c.附近出现极小值,可用相干交换散射模型说明,热电势率在77—380K间为负值,可用Mott s-d 散射模型解释:高温电阻率与温度关系和Ziman理论不一致,是相分离的结果; 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.
