摘要：

We study spin and charge transport properties of the noncentrosymmetric superconductors under magnetic fields with exchange potential (a time-reversal breaking system), where only (P-x +/- ip(y))-wave pair potential is considered. We find that the angle resolved spin conductance as a function of incident angle has a peak and it is not an odd function of incident angle. The angle averaged normalized spin conductance as a function of bias voltage has non-zero value under magnetic fields. The angle averaged normalized charge conductance as a function of bias voltage has a zero bias conductance peak under magnetic field. (C) 2010 Elsevier B.V. All rights reserved.
