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…
On the influence of nanometer-thin antiferromagnetic surface layer on ferromagnetic CrO
Pintu Das, Ashna Bajpai, Yuzo Ohno +2
We present magnetic stray field measurements performed on a single micro-crystal of the half metallic ferromagnet CrO, covered by a naturally grown 2\,-\,5\,nm surface layer of…
Magnetization dynamics of a CrO grain studied by micro-Hall magnetometry
Pintu Das, Fabrizio. Porrati, Steffen Wirth +5
Micro-Hall magnetometry is employed to study the magnetization dynamics of a single, micron-size CrO grain. With this technique we track the motion of a single domain wall, whi…
Band-tail shape and transport near the metal-insulator transition in Si-doped Al(0.3)Ga(0.7)As
Jennifer Misuraca, Jelena Trbovic, Jun Lu +5
In the present work, an infrared LED is used to photodope MBE-grown Si:Al(0.3)Ga(0.7)As, a well known persistent photoconductor, to vary the effective electron concentration of sam…
(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…
