Abstract
We report improvements in the crystallinity of a III-V-based diluted magnet ic semiconductor (Ga, Mn)As by heat treatment (annealing) after growth at c omparatively low temperatures. This method can be used to raise the Curie t emperature to 100 K without the need for severe optimization of growth cond itions, as well as to adjust the material parameters to desired values.
