Resumen:
The transient terahertz radiation emitted by a spin coherence optically generated in CdMnTe two-dimensional electron gases is directly measured in the time domain using electro-optic sampling. The spin radiation decays in a few ps at high magnetic fields. We also provide a full theoretical description within first principle calculations of both the generation of spin waves, precession and emission of THz radiation.
