The spin-relaxation process of A-band exciton in GaN is observed by spin-dependent pump and probe reflectance measurement with subpicosecond time resolution. The spin-relaxation times at 150-225 K are 0.47-0.25 ps. These are at least one order of magnitude shorter than those of the other III-V compound semiconductors. The spin-relaxation time τs is found to be proportional to T-14, where T is the temperature.
