We have performed an in‐situ depth profile photoemission study of Mn‐doped GaN prepared by a low temperature thermal diffusion method. It was revealed from core‐level photoemission spectra that Mn atoms are doped as Mn2+ ions in deep regions of the GaN substrates. In magnetization measurements, weak hysteresis was detected in samples using p‐type GaN substrates while samples using n‐type GaN substrates showed only paramagnetism.
