Definitive Evidence of Interlayer Coupling Between (Ga,Mn)As Layers Separated by a Nonmagnetic Spacer
B. J. Kirby, J. A. Borchers, X. Liu +3
We have used polarized neutron reflectometry to study the structural and magnetic properties of the individual layers in a series of (Al,Be,Ga)As/(Ga,Mn)As/GaAs/(Ga,Mn)As multilaye…
Weak localization in GaMnAs: evidence of impurity band transport
L. P. Rokhinson, Y. Lyanda-Geller, Z. Ge +4
We report the observation of negative magnetoresistance in the ferromagnetic semiconductor GaMnAs at low temperatures ( K) and low magnetic fields ( mT). We attribut…
Magnetic Anisotropy, Spin Pinning and Exchange Constants of (Ga,Mn)As films
Ying-Yuan Zhou, Yong-Jin Cho, Zhiguo Ge +3
We present a detailed investigation of exchange-dominated nonpropagating spin-wave modes in a series of 100 nm GaMnAs films with Mn concentrations ranging from…
Effects of Capping on the (Ga,Mn)As Magnetic Depth Profile
B. J. Kirby, J. A. Borchers, J. J. Rhyne +6
Annealing can increase the Curie temperature and net magnetization in uncapped (Ga,Mn)As films, effects that are suppressed when the films are capped with GaAs. Previous polarized…
