  We present the direct measurements of magnetoexciton transport. Excitons give
the opportunity to realize the high magnetic field regime for composite bosons
with magnetic fields of a few Tesla. Long lifetimes of indirect excitons allow
the study kinetics of magnetoexciton transport with time-resolved optical
imaging of exciton photoluminescence. We performed spatially, spectrally, and
time-resolved optical imaging of transport of indirect excitons in high
magnetic fields. We observed that increasing magnetic field slows down
magnetoexciton transport. The time-resolved measurements of the magnetoexciton
transport distance allowed for an experimental estimation of the magnetoexciton
diffusion coefficient. An enhancement of the exciton photoluminescence energy
at the laser excitation spot was found to anti-correlate with the exciton
transport distance. A theoretical model of indirect magnetoexciton transport is
presented and is in agreement with the experimental data.
