Experimental measurement of microwave-induced electron spin-flip time

, 2001
The electron spin resonance (ESR) is optically detected by monitoring the microwave-induced changes in the circular polarization of the neutral exciton (X) and the negatively charged exciton (X-) emission in CdTe quantum wells with low density of excess ...

Hyperfine-mediated spin-flip transitions in GaAs quantum dots

, 2002
Spin-flip rates in GaAs quantum dots can be quite slow, thus opening up the possibilities to manipulate spin states in the dots. We present here estimations of inelastic spin-flip rates mediated by hyperfine interaction with nuclei.

Spin-flip component of the pomeron

Physics Letters B, 1989
Abstract The spin-flip pomeron amplitude is estimated in the Born approximation of QCD using the nonrelativistic quark model for the nucleon wave function. A nonzero result is possible if the nucleon contains a dynamically enhanced component with a compact diquark. The proposed model-independent way of the pomeron spin-flip measurement in the Coulomb-

Landau level spin diode in a GaAs two dimensional hole system

New Journal of Physics, 2015
We have fabricated and characterized a Landau level spin diode in a GaAs two-dimensional hole system. We used the spin diode to probe the hyperfine coupling between hole and nuclear spins and found no detectable net nuclear spin polarization, indicating ...

A Combined Spin-Flip and IP/EA Approach for Handling Spin and Spatial Degeneracies: Application to Double Exchange Systems

, 2018
Many multiconfigurational systems, such as single-molecule magnets, are difficult to study using traditional computational methods due to the simultaneous existence of both spin and spatial degeneracies.

A spin flipper for reversal of polarisation in a thermal atomic beam

, 1983
Schröder W, Baum G. A spin flipper for reversal of polarisation in a thermal atomic beam. J.Phys. E. 1983;16(1):52-56.By using the method of diabatic passage, we developed a spin flipper which allows a rapid and convenient reversal of the atomic spins ...

Spin transport of excitons [PDF]

, 2009
We report on observation of the spin transport of spatially indirect excitons in GaAs/AlGaAs coupled quantum wells (CQW). Exciton spin transport over substantial distances, up to several micrometers in the present work, is achieved due to orders of ...

Unraveling the dynamics of magnetization in topological insulator-ferromagnet heterostructures via spin-orbit torque

npj Spintronics
Spin–orbit coupling is a relativistic effect coupling the orbital angular momentum with the spin, which determines the physical properties of condensed matter.
