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.
