Electron-Spin-Echo Envelope Modulation - NASA/ADS.

The electron spin-echo (ESE) signal decay of paramagnetic centers induced by their dipole-dipole interaction modulated simultaneously by the processes of random spin flips (the spectral diffusion.

Electron spin echo modulation study of AOT reverse micelles.

Electron Spin Echo Envelope Modulation (ESEEM) spectroscopy is a powerful technique for the study of hyperfine interactions between an unpaired electron and nearby nuclei in solids, and is employed in quantitative structural studies. Here, we describe the use of ESEEM to study the slow motion of deu. Electron spin echo dephasing is produced by electron spectral diffusion mainly, with a small contribution from instantaneous diffusion for all spin transitions. For the highest field transition (-5/2↔-3/2) an additional contribution from nuclear spectral diffusion appears with resonance type enhancement at low temperatures.

Robust millisecond coherence times of erbium electron spins.

An electron spin echo envelope modulation frequency analysis is performed of the 14 N and 15 N bacteriochlorophyll a + cation in solid solution. Hyperfine couplings of 2.0 and 3.1 MHz are derived which correspond to the perpendicular component of the axial hyperfine coupling tensor. Seven quadrupole frequencies were measured, six of which group.

Sorted by... reduction in optical pumping power for a room-temperature maser by coupling a strontium titanate resonator with the spin-polarized population inversion provided by triplet states in an optically excited pentacene-doped. Spin echo is widely used in bulk electron spin resonance (ESR) experiments to study interactions and to determine the structure of complex molecules ().Recently, local contact interactions were observed between single-NV electronic spins and the nuclear spins associated with the host nitrogen and the nearest-neighbor carbon atoms (3, 24).

X- and Q-Band Electron Spin Echo Study of Stochastic Molecular.

The U.S. Department of Energy's Office of Scientific and Technical Information. Genetically-engineered human carbonic anhydrase II mutants have been prepared with cysteine introduced at selected locations and spin-labeled with an aminoxyl (formerly known as nitroxide) radical. Two-pulse electron spin echo data have been obtained for samples in 1∶1 water–glycerol employing a Bruker ESP380E spec.

We report a measurement of the spin-echo decay of a single electron spin confined in a semiconductor quantum dot. When we tip the spin in the transverse plane via a magnetic field burst, it dephases in 37 ns due to the Larmor precession around a random effective field from the nuclear spins in the host material. We reverse this dephasing to a large extent via a spin-echo pulse, and find a spin.

Electron spin echo detection of stochastic molecular.

Quantum mechanicalproperties of the electron include an intrinsic angular momentum(spin) of a half-integer value, expressed in units of the reduced Planck constant, ħ. Being fermions, no two electrons can occupy the same quantum state, in accordance with the Pauli exclusion principle.[10].

Intramembrane Polarity by Electron Spin Echo Spectroscopy of.

Time domain and pulsed electron magnetic resonance (EMR) have become important and experimentally facile techniques in biology and chemistry because the technology of microwave circuits has advanced to the state where pulse sequences can be synthesized on a time scale that is commensurate to the state-to-state dynamics of the electron spin. For this reason it is now.

Electron- phonon Interactions Itinerant Magnets Molecular Motions Coh er nt Modes in Gla se and Liquids SPSS - Chopper Spectrometer Neutron Spin Echo has significantly extended the (Q,E) range to which neutron scattering can be applied The Underlying Physics of Neutron Spin Echo (NSE) Technology is Larmor Precession of the Neutron’s Spin. A number of microwave pulse sequences (e.g. two- pulse, three- pulse,...) are able to create an electron spin echo. When the time between two of these pulses is increased, the echo is usually found to decay exponentially. This decay is determined by spin- lattice and/or spin- spin relaxation (depending on the sequence used). Where S=(S x, S y, S z) is the spin-1 operator of the vacancy electron spin, I z is the z component of the spin-1/2 operator of the 14 N nuclear spin, D=(2π × )2.87 GHz is the axial zero-field.

This results in one of the lowest nuclear magnetic moment densities among natural-abundance crystals, leading to recent predictions that a Hahn echo electron spin coherence time of 20 ms should be achievable in this matrix. To characterize spin coherence, we rely throughout this article on the Hahn echo pulse sequence, because its widespread.
