Abstract
We have investigated the Mn acceptor state of III-V-based diluted magnetic semiconductor Ga 1-xMn xAs by means of high-resolution resonant x-ray emission spectroscopy, across the Mn L 3 edge. We identify the coexistence of signals related to the neutral impurity A 0 and the ionized acceptor state A - in Ga 1-xMn xAs. This fact suggests that double-exchange-like interaction exists in the ferromagnetic coupling in addition to the free-carrier-induced interaction.
