Exchange Biasing of the Ferromagnetic Semiconductor (Ga,Mn)As by MnO
K. F. Eid, M. B. Stone, O. Maksimov +6
We provide an overview of progress on the exchange biasing of a ferromagnetic semiconductor (Ga1-xMnxAs) by proximity to an antiferromagnetic oxide layer (MnO). We present a detail…
Magnetoresistance Anomalies in (Ga,Mn)As Epilayers with Perpendicular Magnetic Anisotropy
G. Xiang, A. W. Holleitner, B. L. Sheu +5
We report the observation of anomalies in the longitudinal magnetoresistance of tensile-strained (Ga,Mn)As epilayers with perpendicular magnetic anisotropy. Magnetoresistance measu…
Nanoengineered Curie Temperature in Laterally-Patterned Ferromagnetic Semiconductor Heterostructures
K. F. Eid, B. L. Sheu, O. Maksimov +3
We demonstrate the manipulation of the Curie temperature of buried layers of the ferromagnetic semiconductor (Ga,Mn)As using nanolithography to enhance the effect of annealing. Pat…
Annealing-dependence of Exchange Bias in MnO/Ga1-xMnxAs Heterostructures
K. F. Eid, O. Maksimov, M. B. Stone +2
We discuss the annealing-dependence of exchange bias in Ga1-xMnxAs epilayers that are overgrown with Mn. Although pure Mn is a known antiferromagnet, we find that the as-grown Mn o…
