摘要
We report the results of a comprehensive study of weak localization and electron-electron interaction effects in disordered V1-xPdx alloys whose compositions are close to the (low T-c) A15 V3Pd compound. Magnetoresistivity and zero field resistivity have been measured within the temperature range 1.5 <= T <= 300 K. The low-temperature resistivity obeys a p(o)(5/2)T(1/2) law, which is explained by electron-electron interaction. We have determined the electron-phonon scattering time (tau(e-Ph)) for V1-xPdx alloys. Our results indicate an anomalous electron-phonon scattering rate tau(-1)(e-ph) obeying quadratic temperature dependence. This observation is interpreted by the existing theories of electron-phonon interactions. (c) 2004 Elsevier Ltd. All rights reserved.
