Anomalous temperature coefficient of electrical resistivity of disordered V1-xAlx and V1-xAlx-yFey alloys

We have demonstrated the correlation between the temperature coefficient of electrical resistivity (alpha(T)) and electron mean free path (l(e)) for disordered V1-xAlx and V1-xAlx-yFey alloys at room temperature in the light of the two quantum mechanical effects like weak localization and electron-electron interaction. The critical resistivity (rho(c)) of the alloys having temperature exponent of inelastic scattering length, p = 1, is not influenced by the electron-electron interaction.
