We report a systematic study of the low-temperature electrical resistivity
of epitaxial nanometric SrRuO3 and LaNiO3 thin films. Weak
localization effects were taken into account in order to explain the
presence of minima in the –T curves. This description can be
rationalized by the fact that, at the given growth conditions, the mean free
path was comparable to the Fermi wavelength of the carriers, so that effects
arising from quantum interference of the electronic wavefunctions were
expected. The results reported here are of special interest to understand
the relevance of weak localization effects in oxides.
