Abstract

The resistivity of epitaxial La_0.7Ca_0.3MnO₃ films deposited on SrTiO₃ shows an upturn at low temperatures that is enhanced by the application of a strong magnetic field. This can be understood within the theory of quantum interference effects taking both the interaction and the weak localization correction into account.
