MAGNETIC QUENCHING OF TIME-REVERSED LIGHT IN PHOTOREFRACTIVE DILUTED MAGNETIC SEMICONDUCTORS

Magnetic fields selectively quench phase conjugation during photorefra ctive four-wave mixing experiments in the diluted magnetic semiconduct or Cd1-xMnxTe. Phase conjugation using circularly polarized light fiel ds differentiates between the time-reversed and non-time-reversed comp onents of the four-wave mixing signal. The experimental results establ ish the connection between the removal of time-reversal symmetry in th e solid state by magnetic fields and the magnetic-field-induced quench ing of time-reversed phase-conjugate light.
