Abstract
The magnetoconductivity of p-type CuGaTe2, in metallic regime, has been mea sured at low temperatures in a magnetic field up to 20 T. The experimental data are analyzed in the framework of models that take into account the eff ect of weak localization and electron-electron interactions. Good agreement of the experimental data with theory is found. From the theoretical fit, b oth the inelastic and spin-orbit relaxation times are estimated and their d ependence on temperature established.
