Low-temperature magnetization of (Ga,Mn)As semiconductors
T. Jungwirth, J. Masek, K. Y. Wang +12
We report on a comprehensive study of the ferromagnetic moment per Mn atom in (Ga,Mn)As ferromagnetic semiconductors. Theoretical discussion is based on microscopic calculations an…
Anisotropic Magnetoresistance and Magnetic Anisotropy in High-quality (Ga,Mn)As Films
K. Y. Wang, K. W. Edmonds, R. P. Campion +3
We have performed a systematic investigation of magnetotransport of a series of as-grown and annealed Ga1-xMnxAs samples with 0.011 <= x <= 0.09. We find that the anisotropic magne…
Prospects of high temperature ferromagnetism in (Ga,Mn)As semiconductors
T. Jungwirth, K. Y. Wang, J. Masek +11
We report on a comprehensive combined experimental and theoretical study of Curie temperature trends in (Ga,Mn)As ferromagnetic semiconductors. Broad agreement between theoretical…
Intrinsic and Extrinsic Contributions to the Lattice Parameter of GaMnAs
L. X. Zhao, C. R. Staddon, K. Y. Wang +4
We report on measurements of the crystal structure and hole density in a series of as-grown and annealed GaMnAs samples. The measured hole densities are used to obtain the fraction…
