Weak electron localization and electron-electron interaction effects in metallic glasses at temperatures just above superconducting transition

Electrical resistance and magnetoresistance (MR) of metallic glasses Zr_xBe_1−x (x = 0.6; 0.7) and Zr₇₅Rh₂₅ in the temperature range of 4.2–12 K and in the magnetic field of 7.4T have been studied. It has experimentally been shown that in accordance with the theory of weak localization of electrons (WEL) and electron-electron interaction (EEI) temperature dependences of conductivity and magnetic conductivity (MC) are determined by localization effects and EEI in the Cooper and Diffusion channels. The comparison of theoretical and experimental values of coefficients at temperature laws of the conductivity variation points out to the need to take into account the Maki-Thompson (MT) temperature correction in the absence of a magnetic field.
