Abstract
Calculations of electrons in a remotely doped wide parabolic quantum well, in the presence of a strong in-plane magnetic field, using a modified Hartree-Fock approximation with a point-contact exchange interaction, support the idea that a spin-density-wave state may occur in an experimentally accessible range of parameters. Electrical transport in the spin-density-wave state is expected to be finite at zero temperature, but highly anisotropic, with a low resistivity for currents perpendicular to the magnetic field.Keywords
