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…
Spin-polarized Tunneling in Hybrid Metal-Semiconductor Magnetic Tunnel Junctions
S. H. Chun, S. J. Potashnik, K. C. Ku +2
We demonstrate efficient spin-polarized tunneling between a ferromagnetic metal and a ferromagnetic semiconductor with highly mismatched conductivities. This is indicated by a larg…
Saturated Ferromagnetism and Magnetization Deficit in Optimally Annealed (Ga,Mn)As Epilayers
S. J. Potashnik, K. C. Ku, R. Mahendiran +4
We examine the Mn concentration dependence of the electronic and magnetic properties of optimally annealed Ga1-xMnxAs epilayers for 1.35% < x < 8.3%. The Curie temperature (Tc), co…
Above-Room-Temperature Ferromagnetism in GaSb/Mn Digital Alloys
X. Chen, M. Na, M. Cheon +9
Digital alloys of GaSb/Mn have been fabricated by molecular beam epitaxy. Transmission electron micrographs showed good crystal quality with individual Mn-containing layers well re…
