摘要：

Transport properties of Nd2-xCexCuO4+delta/SrTiO3 single crystal films (B parallel to c;J parallel to ab) are investigated in magnetic fields B up to 9T at T = (0.4-4.2) K. An analysis of normal state (at B > B-c2) Hall coefficient R-H(n) dependence on Ce doping takes us to a conclusion about the existence both of electron-like and hole-like contributions to transport in nominally electron-doped system. In accordance with R-H(n)(x) analysis an anomalous sign reversal of Hall effect in mixed state at B < B-c2 may be ascribed to a flux-flow regime for two types of carriers with opposite charges.
