Heiman, D

Stimulated emission of near-band-gap radiation is observed in the semimagnetic semiconductor Cd/sub 1-x/Mn/sub x/Se, x = 0.1. Excitation was achieved by optical pumping just below the absorption edge. The photon energy of the recombination emission is a strong function of both magnetic field and temperature. With increasing field, the emission shifts to lower energy. The shift is primarily proportional to the Mn/sup + +/ magnetization and at high fields saturates at approximately 60 meV. The magnitude is in reasonable agreement with that expected from the exchange energies.
