NUCLEAR-SPIN OR ELECTRON-SPIN MAGNETOMETERPROBLEM TO BE SOLVED: To improve a nuclear-spin or electron-spin magnetometer which is used to measure a magnetic field.;SOLUTION: The nuclear-spin or electron-spin magnetometer comprises a probe (103) which has a resonance frequency (γ.Bm) related to...
The effects of cross-correlation between Curie spin–nuclear dipole and nuclear dipole–nuclear dipole interactions on the linewidths and resonance frequencies of the individual lines of an AX multiplet in paramagnetic systems have been calculated. The implication of the relaxation-induced frequency shift...
Nuclear spin relaxation in some S = 1/2 paramagnetic transition-metal complexes is considered. If rotational reorientation dominates the electron and nuclear spin relaxation processes current theoretical treatments of spin relaxation provide an adequate description of the spin relaxation. However, there are...
Electron and nuclear spin dynamics are measured using a pump-delay-probe protocol (Fig. 1c). The decay of optically pumped electron [nuclear] spin polarisation over dark period TDark is probed by measuring IResFl [Ehf]. Figure 1d shows an example of time-resolved ResFl, which is used to...
We show that by switching the driving phase synchronously with the precession of a given nuclear spin, the interaction to this spin is selectively enhanced, while the rest of the bath remains decoupled. The enhancement is of resonant character. The key feature of the suggested scheme is that ...
Electron spin resonance (ESR), electron-nuclear double resonance (ENDOR) and general triple resonance were combined to study linewidth differences observed in the ESR spectra of COspecies in calcium carbonate and carbonated apatite. In the latter compound, the motion and a distribution of g-factors...
However, interactions between neighboring qubits are “always on,” and although the electron spin coherence times can be several hundred microseconds, these are still much shorter than typical times for nuclear spins. Here we implement an electron-nuclear hybrid scheme which uses coherent transfer ...
Physical implementations of ESR on individual bound electronic spins have proven to be successful in GaAs-based QD transport experiments5,6, where the essential role of the spin (Pauli) blockade and the nuclear spin bath in that systems were established. However, spin detection via electronic ...
nuclear spins, the so calledhyperfine coupling. In case of the commonly usednitroxideradicals (.O-NRR’) in biological samples, the hyperfine coupling between the electron spin (S = 1/2) and the nitrogen nuclear spin (I = 1) results in the splitting of the signal...
We magnetically and electrically control spin coupling between electrons and nuclei in a vertical GaAs double quantum dot in the Pauli spin blockade regime to characterize the two-electron exchange energy and the dynamic nuclear polarization (DNP). The Pauli blockade is lifted by a hyperfine-mediated...
