%X Magnetization patterning by injection of nonequilibrium electron spins in paramagnetic diluted magnetic semiconductors is studied theoretically. The system is shown to undergo an instability in a region of the parameter space defined by the carriers generation rate and magnetic field. The bifurcation is found to be of subcritical nature. Existing experimental results are examined within this model and experiments are proposed.
