Abstract
We have calculated spin-split electron wave functions and eigenenergies in a wide parabolic quantum well. Our calculation incorporates scattering, a range of many-body approximations, and an applied perpendicular magnetic field. We find unexpected behavior in the spectra due to the spin effects. This behavior includes an abrupt spin polarization of the system at high magnetic fields and a spin-inversion regime where net spin alignment strongly varies across the well. The spin polarization exhibits hysteretic behavior and sensitivity to scattering. The onset and magnitude of the spin inversion depends on the physical parameters of the well as well as the potential approximations.
