. In addition, there#x27;s the magnetic interaction between electron and nucleus so-called hyperfine splitting. This leads to overall four energy levels depending on the electronic and nuclear spin. Pulsed electron paramagnetic resonance EPR is an electron paramagnetic resonance technique that involves the alignment of the net magnetization vector of the electron spins in a constant magnetic field.This alignment is perturbed by applying a short oscillating field, usually a microwave pulse. One can then measure the emitted microwave signal which is created by the sample magnetization.
Microwave-assisted cross-polarization of nuclear spin ensembles.
The polarization process of the nucleus still occurs when the microwave irradiation excites the Double Quantum or Zero Quantum transition, but due to the fact that the sample is spinning, this condition is only met for a short time at each rotor cycle which makes it periodical. May 14, 2021 Physics 14, 73 A small device performs rotational measurements using nuclear spins in a diamond wafer, paving the way for microchip-size gyroscopes. Tom/ Hold that tilt. Like a toy gyroscope, the nuclear spins inside a diamond crystal maintain a stable orientationwhich can be used to measure rotations. The nuclear spin-rotation constant C I Sn has been determined for these isotopomers for the first time and these constants have been related to nmr shielding parameters. A multi-isotopomer analysis, including data from the 120 Sn 17 O and 120 Sn 18 O isotopomers, has been performed on the data.

Cooke, S. , Gerry, M. , Brugh, D. and Suenram, R. 2004, The Rotational Spectrum, Nuclear Field Shift. Resonance can also be achieved by microwave driving of the electron spin of the NV with a Rabi frequency that matches the nuclear spin Larmor frequency Hartmann-Hahn condition [19, 20]. Furthermore it is possible to realise polarisation transfer by the solid effect driving a forbidden double quantum transition thus inducing electron and.

. In our scenario, the electron spin interacts with a 31 P defect nuclear spin via the hyperfine interaction. We theoretically investigate the influence of the P nuclear spin state on the microwave transmission through the cavity and show that nuclear spin readout is feasible with current state-of-the-art devices. Moreover, we identify optimal. On nuclear polarization, the degree of microwave saturation and of electron-nucleus contact has a totally di erent impact on electron polarization, which is of course strongly correlated to the e ectiveness of saturation and almost insensitive, at the steady state, to the magnitude of the interactions between the two spin reservoirs.

A system comprising a solid state lattice containing an electronic spin coupled to a nuclear spin; an optical excitation configuration which is arranged to generate first optical radiation to excite the electronic spin to emit output optical radiation without decoupling the electronic and nuclear spins; wherein the optical excitation configuration is further arranged to generate second optical. The nuclear spin is controlled via microwave-driven, dynamical decoupling DD sequences on the electronic spin, realizing one-qubit and two-qubit gate operations that let us probe the coupling strength and coherent dynamics of the nuclear spin. The optimum conditions for efficient and coherent microwave manipulation of the state of the 13 nuclear spin in such systems are determined and interpreted. INTRODUCTION The ability to create, control and measure coherent states of multispin systems in solids is crucial for quantum information processing, magnetometry, metrology, and so on.
