The transverse magnetoresistance of disordered Zr{sub 1{minus}x}Rh{sub x} thin films has been measured above the superconducting transition temperature T{sub c} as a function of temperature in a magnetic field up to 60 kG. The investigated films are disordered enough to indicate quantum corrections due to localization and electron-electron interaction effects. The field and temperature dependence of the observed magnetoresistance is interpreted in terms of weak-localization, Aslamazov-Larkin, and Maki-Thompson superconducting fluctuations effects. From the comparison of the experimental results with theoretical calculations, the electron-electron attraction strength, {beta}(T/T{sub c}), is derived and is in good agreement with Larkin{close_quote}s theory. The total phase- breaking rate {tau}{sub {var_phi}}{sup {minus}1} has been estimated and ascribed to electron-phonon, electron-electron, electron-fluctuation, and spin-flip scattering mechanisms. {copyright} {ital 1997} {ital The American Physical Society}
