Query: Bulk inversion asymmetry induced magnetogyrotropic reflection from
  quantum wells   Bulk inversion asymmetry (BIA) of III-V and II-VI semiconductor quantum wells
is demonstrated by reflection experiments in magnetic field oriented in the
structure plane. The linear in the magnetic field contribution to the
reflection coefficients is measured at oblique incidence of $s$ and $p$
polarized light in vicinity of exciton resonances. We demonstrate that this
contribution to the reflection is caused by magnetogyrotropy of quantum wells,
i.e. by the terms in the optical response which are linear in both the magnetic
field strength and light wavevector. Theory of magnetogyrotropic effects in
light reflection is developed with account for linear in momentum BIA induced
terms in the electron and hole effective Hamiltonians. Theoretical estimates
agree with the experimental findings. We have found the electron BIA splitting
constant in both GaAs and CdTe based quantum wells is about three times smaller
than that for heavy holes.
