Analysis of the magnetoresistance of three-dimensional amorphous metals with weak localization and electron-electron interaction theories

Abstract

The magnetoresistance of three-dimensional amorphous metals with strong spin-orbit scattering is often difficult to fit to present theories of weak localization and electron-electron interaction. Especially, the fitted values are sensitive to various assumptions in the fits and only quite wide ranges for the parameters controlling the phenomena can be given. Two methods to extract the parameters in a less sensitive way are discussed. A good agreement with theory is found. The principal behaviour for the studied strong spin-orbit scattering system is identical to what is found in amorphous metals with weak spin-orbit scattering.
