Imprinting spatial helicity structure of vector vortex beam on spin texture in semiconductors
Jun Ishihara, Takachika Mori, Takuya Suzuki +5
We present the transfer of the spatially variant polarization of topologically structured light to the spatial spin texture in a semiconductor quantum well. The electron spin textu…
Magnetization reversal of dipolar coupled nanomagnets studied by two-dimensional electron gas based micro-Hall magnetometry
N. Keswani, Y. Nakajima, N. Chauhan +6
We report here the results of two-dimensional electron gas based micro-Hall magnetometry measurements and micromagnetic simulations of dipolar coupled nanomagnets of Ni80Fe20 arran…
(In,Ga)As gated-vertical quantum dot with an Al2O3 insulator
Tomohiro Kita, Daichi Chiba, Yuzo Ohno +1
We fabricated a gated-vertical (In,Ga)As quantum dot with an Al2O3 gate insulator deposited using atomic layer deposition and investigated its electrical transport properties at lo…
Modulation of Noise in Submicron GaAs/AlGaAs Hall Devices by Gating
Yongqing Li, Cong Ren, Peng Xiong +3
We present a systematic characterization of fluctuations in submicron Hall devices based on GaAs/AlGaAs two-dimensional electron gas heterostructures at temperatures between 1.5 K…
Anisotropic Electrical Spin Injection in Ferromagnetic Semiconductor Heterostructures
D. K. Young, E. Johnston-Halperin, D. D. Awschalom +2
A fourteen-fold anisotropy in the spin transport efficiency parallel and perpendicular to the charge transport is observed in a vertically-biased (Ga,Mn)As-based spin-polarized lig…
Origin of enhanced dynamic nuclear polarization and all-optical nuclear magnetic resonance in GaAs quantum wells
G. Salis, D. D. Awschalom, Y. Ohno +1
Time-resolved optical measurements of electron-spin dynamics in a (110) GaAs quantum well are used to study the consequences of a strongly anisotropic electron g-tensor, and the or…
