摘要：

The low temperature transport properties of La0.67Sr0.33MnO3 (LSMO) and Nd0.67Sr0.33MnO3 (NSMO) thin films exhibit chracteristics of renormalized electron electron interaction in two-dimension. The contrasting response of the low temperature transport to magnetic field in the LSMO and NSMO films is attributed to the strikingly different sensitivity of the inter-granular transport to magnetic field in LSMO and NSMO films.
