Highly enhanced Curie temperatures in low temperature annealed (Ga,Mn)As epilayers

K. C. Ku, S. J. Potashnik, R. F. Wang +9

We report Curie temperatures up to 150 K in annealed Ga1-xMnxAs epilayers grown with a relatively low As:Ga beam equivalent pressure ratio. A variety of measurements (magnetization…
