Carrier-mediated antiferromagnetic interlayer exchange coupling in diluted magnetic semiconductor multilayers Ga${}_{1-x}$Mn${}_x$As/GaAs:Be

J. -H. Chung, S. J. Chung, Sanghoon Lee +5

We use neutron reflectometry to investigate the interlayer exchange coupling between Ga${}_{0.97}$Mn${}_{0.03}$As ferromagnetic semiconductor layers separated by non-magnetic Be-doped…
