A Tunable Anomalous Hall Effect in a Non-Ferromagnetic System
J. Cumings, L. S. Moore, H. T. Chou +4
We measure the low-field Hall resistivity of a magnetically-doped two-dimensional electron gas as a function of temperature and electrically-gated carrier density. Comparing these…
Enhancement of Spin Coherence using Q-factor Engineering in Semiconductor Microdisk Lasers
S. Ghosh, W. H. Wang, F. M. Mendoza +5
Semiconductor microcavities offer unique means of controlling light-matter interactions, which have led to the development of a wide range of applications in optical communications…
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…
Andreev Reflection and Pair Breaking Effects at the Superconductor/Magnetic Semiconductor Interface
R. P. Panguluri, K. C. Ku, T. Wojtowicz +5
We investigate the applicability of spin polarization measurements using Andreev reflection in a point contact geometry in heavily doped dilute magnetic semiconductors, such as (Ga…
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…
