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…
Fabrication and Characterization of Modulation-Doped ZnSe/(Zn,Cd)Se (110) Quantum Wells: A New System for Spin Coherence Studies
K. C. Ku, S. H. Chun. W. H. Wang, W. Fadgen +4
We describe the growth of modulation-doped ZnSe/(Zn,Cd)Se quantum wells on (110) GaAs substrates. Unlike the well-known protocol for the epitaxy of ZnSe-based quantum structures on…
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…
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…
Optoelectronic control of spin dynamics at near-THz frequencies in magnetically doped quantum wells
R. C. Myers, K. C. Ku, X. Li +2
We use time-resolved Kerr rotation to demonstrate the optical and electronic tuning of both the electronic and local moment (Mn) spin dynamics in electrically gated parabolic quant…
Exchange Biasing of the Ferromagnetic Semiconductor Ga1-xMnxAs
K. F. Eid, M. B. Stone, K. C. Ku +4
We demonstrate the exchange coupling of a ferromagnetic semiconductor (Ga1-xMnxAs) with an overgrown antiferromagnet (MnO). Unlike most conventional exchange biased systems, the bl…
