Large Nonlinear Kerr Angle in non-Centrosymmetric Fe/AlGaAs (001)Heterostructure
Haibin Zhao, Diyar Talbayev, Gunter Luepke +3
A large nonlinear magneto-optical effect is observed in a non-centrosymmetric Fe/AlGaAs (001) heterostructure. This effect is a direct consequence of interference between second-ha…
Determination of Interface Atomic Structure and Its Impact on Spin Transport Using Z-Contrast Microscopy and Density-Functional Theory
Thomas J. Zega, Aubrey T. Hanbicki, Steven C. Erwin +5
We combine Z-contrast scanning transmission electron microscopy with density-functional-theory calculations to determine the atomic structure of the Fe/AlGaAs interface in spin-pol…
Electrical Spin Pumping of Quantum Dots at Room Temperature
C. H. Li, G. Kioseoglou, O. M. J. van t Erve +7
We report electrical control of the spin polarization of InAs/GaAs self-assembled quantum dots (QDs) at room temperature. This is achieved by electrical injection of spin-polarized…
Epitaxial Growth of the Diluted Magnetic Semiconductors CryGe1-y and CryMnxGe1-x-y
G. Kioseoglou, A. T. Hanbicki, C. H. Li +3
We report the epitaxial growth of CryGe1-y and CryMnxGe1-x-y(001) thin films on GaAs(001), describe the structural and transport properties, and compare the measured magnetic prope…
Analysis of the Transport Process Providing Spin Injection through an Fe/AlGaAs Schottky Barrier
A. T. Hanbicki, O. M. J. van t Erve, R. Magno +7
Electron spin polarizations of 32% are obtained in a GaAs quantum well via electrical injection through a reverse-biased Fe/AlGaAs Schottky contact. An analysis of the transport da…
