Coercive Field and Magnetization Deficit in Ga(1-x)Mn(x)As Epilayers

S. J. Potashnik, K. C. Ku, S. H. Chun +4

We have studied the field dependence of the magnetization in epilayers of the diluted magnetic semiconductor Ga(1-x)Mn(x)As for 0.0135 < x < 0.083. Measurements of the low temperat…

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…
