We show that in the metallic phase of a two dimensional electron gas thespin-orbit coupling due to structure inversion asymmetry leads to acharacteristic anisotropy in the magnetoconductance. Within the assumption thatthe metallic phase can be described by a Fermi liquid, we compute theconductivity in the presence of an in-plane magnetic field. Both the spin-orbitcoupling and the Zeeman coupling with the magnetic field give rise to two spinsubbands, in terms of which most of the transport properties can be discussed.  The strongest conductivity anisotropy occurs for Zeeman energies of the orderof the Fermi energy corresponding to the depopulation of the upper spinsubband. The energy scale associated with the spin-orbit coupling controls thestrength of the effect. More in particular, we find that the detailed behaviorand the sign of the anisotropy depends on the underlying scattering mechanism.Assuming small angle scattering to be the dominant scattering mechanism ourresults agree with recent measurement on Si-MOSFET's in the vicinity of themetal-insulator transition.Comment: 13 pages, 12 Figures, RevTeX, submitted to EPJ
