  We investigated possibility of using local magnetic field originating from
ferromagnetic island deposited on the top of semiconductor quantum well to
produce zero- and one-dimensional traps for quasi-particles with spin. In
particular we considered two shapes of experimentally made magnets -
cylindrical and rectangular. In the case of ferromagnetic micro-disk the trap
can localize spin in three dimensions, contrary to the rectangular micro-magnet
which creates a trap that allows free propagation in one direction. We present
in detail prediction for absorption spectrum around the main absorption edge in
both type of micro-magnets.
