title: Low temperature conductivity in ferromagnetic manganite thin films: quantum corrections and inter-granular transport.
abstract: The interplay between inter-granular transport and quantum corrections to low temperature transport properties of La(0.67)Sr(0.33)MnO(3) (LSMO) and Nd(0.67)Sr(0.33)MnO(3) (NSMO) thin films has been discussed. All the samples exhibit characteristics of renormalized electron-electron interaction in two dimensions. The contrasting response of the low temperature transport to magnetic field in the LSMO and NSMO films is attributed to the strikingly different magnetic field sensitivity of the inter-granular transport.
