Abstract
Dynamic phase separation in CdMnTe quantum wells under femtosecond pulse excitation leads to formation of hot and cold spin domains. Using Fourier spectroscopy of the time-resolved magneto-optical Kerr effect we determine the temperatures and the total areas of each kind of domain. The instability is shown to be triggered by the magnetic field above a threshold value.
