Unexpected Anisotropic Two Dimensional Electron Gas at the LaAlO3/SrTiO3 (110) Interface
A. Annadi, X. Wang, K. Gopinadhan +17
The observation of a two dimensional electron gas (2DEG) (1, 2), superconductivity (3, 4), magnetic effects (5) and electronic phase separation (6-8) at the interfaces of insulatin…
Strong Suppression of the Spin Hall Effect in the Spin Glass State
Y. Niimi, M. Kimata, Y. Omori +5
We have measured spin Hall effects in spin glass metals, CuMnBi alloys, with the spin absorption method in the lateral spin valve structure. Far above the spin glass temperature Tg…
New Diluted ferromagnetic semiconductor Li(Zn,Mn)P with decoupled charge and spin doping
Z. Deng, K. Zhao, B. Gu +15
We report the discovery of a new diluted magnetic semiconductor, Li(Zn,Mn)P, in which charge and spin are introduced independently via lithium off-stoichiometry and the isovalent s…
Surface-assisted Spin Hall Effect in Au Films with Pt Impurities
B. Gu, I. Sugai, T. Ziman +5
We show, both experimentally and theoretically, a novel route to obtain giant room temperature spin Hall effect due to surface-assisted skew scattering. In the experiment, we repor…
Theory of the spin Hall effect, and its inverse, in a ferromagnetic metal near the Curie temperature
B. Gu, T. Ziman, S. Maekawa
We give a theory of the inverse spin Hall effect (ISHE) in ferromagnetic metals based on skew scattering via collective spin fluctuations. This extends Kondo's theory of the anomal…
On the fractal dimension of non-Newtonian Hele-Shaw flow subject to Saffman-Taylor instability
J. Adriazola, B. Gu, L. Cummings +1
We introduce a discrete numerical method based on the diffusion-limited aggregation (DLA) approach to simulate two-fluid Hele-Shaw flow subject to the Saffman-Taylor interfacial in…
The spin Hall effect as a probe of nonlinear spin fluctuations
D. H. Wei, Y. Niimi, B. Gu +3
The spin Hall effect and its inverse play key roles in spintronic devices since they allow conversion of charge currents to and from spin currents. The conversion efficiency strong…
