  Magnetoresistance results are presented for p-SiGe samples on the metallic
side of the B=0 metal-insulator transition. The results cannot be understood
within the framework of standard theories for quantum corrections of a weakly
interacting 2- dimensional system. In particular no logarithmic dependence on
temperature is observed, at low fields, in either the longitudinal or Hall
resistivities despite evidence in the magnetoresistance of weak localisation
effects. Further, the Hall coefficient shows a strong logarithmic dependence on
field. The results are better explain by renormalisation group theories and by
an anomalous Hall effect associated with strong spin-orbit coupling in the
presence of a background spin texture.
