An electric field applied to a two-dimensional electron gas with
spin-orbit coupling generates spin magnetization. Based on a quantum
kinetic equation, we study the dependence of the magnitude and direction
of the spin magnetization on the strength of a perpendicular magnetic
field. We show that as magnetic field increases, the magnitude of the
magnetization decreases. However, in sufficiently strong magnetic
fields, the magnetization acquires a giant oscillating component; the
amplitude of this component may exceed the magnetization at zero
magnetic field. The large amplitude of magnetization oscillations is
related to the enhanced electron-hole asymmetry in quantizing magnetic
