Probing Single-Electron Spin Decoherence in Quantum Dots using Charged Excitons

open access: yes, 2004
We propose to use optical detection of magnetic resonance (ODMR) to measure the decoherence time T_{2} of a single electron spin in a semiconductor quantum dot.

Electron spin as a spectrometer of nuclear spin noise and other fluctuations

open access: yes, 2006
This chapter describes the relationship between low frequency noise and coherence decay of localized spins in semiconductors. Section 2 establishes a direct relationship between an arbitrary noise spectral function and spin coherence as measured by a ...

Spin-states in MoS2 thin-film transistors distinguished by operando electron spin resonance

open access: yesCommunications Materials, 2021
Identifying the properties of spin-states is crucial for understanding the possible magnetic applications of MoS2 thin-film transistors. Here, spin-states of conduction electrons and atomic vacancies in MoS2 are distinguished and investigated under ...

Electron Paramagnetic Resonance of Single Magnetic Moment on a Surface

open access: yes, 2016
We address electron spin resonance of single magnetic moments in a tunnel junction using time-dependent electric fields and spin-polarized current. We show that the tunneling current directly depends on the local magnetic moment and that the frequency of

Evolution of structural defects in milled Cd0.3Zn0.7 Se powder studied by electron spin spectroscopy

open access: yesResults in Physics, 2017
Mechanically induced defect in high energy milled Cd0.3Zn0.7Se nanocrystals was investigated using electron spin resonance (ESR). The broad ESR component with g ∼ 2 was attributed to paramagnetic defects present in the milled powder.

Observation of conduction electron spin resonance in boron doped diamond [PDF]

open access: yes, 2013
We observe the electron spin resonance of conduction electrons in boron doped (6400 ppm) superconducting diamond (Tc =3.8 K). We clearly identify the benchmarks of conduction electron spin resonance (CESR): the nearly temperature independent ESR signal ...

Demonstration of NV-detected ESR spectroscopy at 115 GHz and 4.2 Tesla [PDF]

open access: yes, 2020
High frequency electron spin resonance (ESR) spectroscopy is an invaluable tool for identification and characterization of spin systems. Nanoscale ESR using the nitrogen-vacancy (NV) center has been demonstrated down to the level of a single spin ...

Harnessing the power of quantum systems based on spin magnetic resonance: from ensembles to single spins

open access: yesAdvances in Physics: X, 2017
Quantum computation provides great speedup over its classical counterpart for certain tasks. Spin system is one of the most important candidates to realize quantum computations.

Spin and charge transports with thermodynamic electron–hole correlation in nearly compensated metals

open access: yesAIP Advances, 2020
The long spin-relaxation time (τs) toward the large transport distance of spin current (SC) is desirable for practical applications of spintronic devices because spatially and temporally large spin coherence makes spin manipulation easier.

Electron doping evolution of the magnetic excitations in BaFe2-xNixAs2

open access: yes, 2013
We use inelastic neutron scattering (INS) spectroscopy to study the magnetic excitations spectra throughout the Brioullion zone in electron-doped iron pnictide superconductors BaFe$_{2-x}$Ni$_{x}$As$_{2}$ with $x=0.096,0.15,0.18$.
