Solving a spintronic mystery over gallium manganese arsenide

"Our results challenge the valence band picture for gallium manganese arsenide and point to the existence of an impurity band, created by even moderate to high doping levels of manganese," Walukiewicz says. "It is the location and partially localized nature of holes within this impurity band that drives the value of the Curie temperature."
