Ultrafast carrier dynamics,in ferromagnetic semiconductors

Two-color, time-resolved reflectivity is used to study femtosecond and picosecond carrier dynamics in III-V ferromagnetic semiconductors. Ultrashort carrier lifetimes, oscillations, and multi-level decay processes were observed. We discuss the dependence of data on the probe wavelength, pump intensity, and sample temperature
