Observation of the antiferromagnetic spin Hall effect

Nature Materials, 2021
The discovery of the spin Hall effect1 enabled the efficient generation and manipulation of the spin current. More recently, the magnetic spin Hall effect2,3 was observed in non-collinear antiferromagnets, where the spin conservation is broken due to the non-collinear spin configuration.

Observation of a Hybrid Spin Resonance

Physical Review Letters, 2000
A new type of spin depolarization resonance has been observed at the Brookhaven Alternating Gradient Synchrotron (AGS). This spin resonance is identified as a strong closed-orbit sideband around the dominant intrinsic spin resonance. The strength of the resonance was proportional to the 9th harmonic component of the horizontal closed orbit and ...

Observation of the spin Seebeck effect

Nature, 2008
The generation of electric voltage by placing a conductor in a temperature gradient is called the Seebeck effect. Its efficiency is represented by the Seebeck coefficient, S, which is defined as the ratio of the generated electric voltage to the temperature difference, and is determined by the scattering rate and the density of the conduction electrons.

Optical observation of single spins in silicon

Nature, 2022
The global quantum internet will require long-lived, telecommunications-band photon-matter interfaces manufactured at scale1. Preliminary quantum networks based on photon-matter interfaces that meet a subset of these demands are encouraging efforts to identify new high-performance alternatives2. Silicon is an ideal host for commercial-scale solid-state

Spin observables at threshold for meson photoproduction

Physical Review C, 1992
Observables in two-body reactions such as cross sections, polarizations, and spin correlations are often of simple form at threshold, since only a few partial waves contribute. Spin observables near threshold for meson photoproduction reactions (with emphasis on the \ensuremath{\gamma}p\ensuremath{\rightarrow}${\mathit{K}}^{+}$\ensuremath{\Lambda} case)

Observation of spin-waves in CuMn spin glasses

Journal of Magnetism and Magnetic Materials, 1983
Abstract In inelastic neutron scattering experiments on Cu Mn single crystals spin-waves were detected in the [100] and [111] directions. The excitation energies are nearly independent of temperature and direction. The observed spin-wave dispersion corresponds to the temperature dependence of the thermodynamic properties at low temperatures.

Spin observables in elastic proton scattering

Physical Review C, 1985
The use of alternative representations of spin observables for elastic scattering is investigated within the context of comparing relativistic and nonrelativistic approaches. The results of calculations of the observables A/sub y/ and Q together with the alternatives S and ..beta..

Observation of Spin-Polarized Photoelectron Diffraction

Physical Review Letters, 1985
We report the first observation of spin-polarized photoelectron diffraction in core-level emission from antiferromagnetic KMn${\mathrm{F}}_{3}$. The Mn $3s$ multiplet splitting provides an internal source of polarized electrons, and spin-polarized photoelectron diffraction effects of up to 17% are seen in the $\frac{^{5}S}{^{7}S}$ intensity ratio ...

Observation of the Spin Hall Effect in Semiconductors

Science, 2004
Electrically induced electron-spin polarization near the edges of a semiconductor channel was detected and imaged with the use of Kerr rotation microscopy. The polarization is out-of-plane and has opposite sign for the two edges, consistent with the predictions of the spin Hall effect.

Spin-spin and tensor observables in the isovector nucleon-nucleon force

Physical Review C, 1989
We justify the inclusion of the rho meson in the Bonn potential in terms of the {ital N{bar N}}{r arrow}{pi}{pi} helicity amplitude analysis. The tensor observables are well reproduced with the resulting interaction. Consequences for the momentum dependence of the spin-longitudinal and spin-transverse effective interactions are discussed.
