Abstract
The Mn-site-projected electronic structure of the diluted magnetic semiconductors (formula presented) (formula presented) 0.038, 0.047, 0.052, 0.058) of as-grown and low-temperature (LT) annealed samples are systematically studied using high-resolution Mn (formula presented) absorption spectroscopy. The study exhibits coexistence of the ferromagnetic (formula presented) ion and the paramagnetic Mn-As complex that transforms into the ferromagnetic component with LT annealing. The ratio of ferromagnetic to paramagnetic components is directly related to the x dependence of the hole density and ferromagnetic critical temperature.
