在 4.2到 2 5K范围内测量了 2 0纳米稀掺杂铜铌超薄膜 (Cu99Nb1 ,Cu95 Nb5 )的电阻及磁导随温度的变化 ,没有观察到超导的迹象 ,而且样品的磁导都表现出典型的弱局域性质 .通过与理论的拟合 ,得到描述弹性散射 ,非弹性散射 ,自旋 轨道散射和磁散射的特征磁场和特征迟豫时间 .Cu95 Nb5 的各种特征迟豫时间均比Cu99Nb1 的小 .铌的加入不仅很大地影响了杂质引起的电子 电子散射 ,同时也是导致样品的弹性散射时间与自旋 轨道散射时间之比τ0 /τso偏离Abrikosov Gorkov关系的主要原因 The resistances and permeabilities of 20 nm thin doped Cu-Nb ultra-thin films (Cu99Nb1, Cu95Nb5) were measured over the temperature range from 4.2 to 25 K and no sign of superconductivity was observed, and the permeance of the samples showed A typical weak local property is obtained.Furthermore, the characteristic magnetic field describing the elastic scattering, the inelastic scattering, the spin-orbit scattering and the magnetic scattering and the characteristic relaxation time are obtained by fitting with the theory.Cu95 Nb5 has various characteristic time Which is smaller than that of Cu99Nb 1. The addition of niobium not only greatly affects the electron-induced electron-scattering but also the main reason that the ratio τ0 / τso of the elastic scattering time and the spin-orbit scattering time deviates from Abrikosov Gorkov
