Preparation of a nuclear spin state is a crucial step to implement a sensor that utilizes a nuclear spin. In a low magnetic field, such a preparation utilizes population transfer, from polarized electronic spin to nuclear spin, using microwave pulses.

The nuclear spin hyperpolarization method includes the steps of: irradiating a sample, prepared by doping solid benzoic acid derivative with a pentacene derivative, placed in a space where a static magnetic field is formed by a main magnetic field forming unit, with a laser beam from a laser source; following the light irradiation, irradiating the sample with a microwave from a microwave.
Microwave ultrasonic measurement of nuclear spin diffusion.
The principle of the proposed DNP process is schematically shown in Fig. 10.8A.For an electron-nuclear e-N spin system with a single unpaired electron S=1/2 and the nuclear spin I=3/2 of a Ga atom, relevant to the spin-filtering Ga i defect, eight relative orientations between the electron and nuclear spins are possible.When the defect-engineered spin filtering is in action, the eight. We show that employing an off-axis magnetic field with a modest amplitude 0.01 T at an angle with respect to the NV natural quantization axes is enough to tilt the direction of the electronic spins, and enable efficient spin exchange with the nitrogen nuclei of the NV center..

As shown in Fig. Fig.4, 4, numerical results for the time dependence of the nuclear polarization for different biradical orientations can mostly be categorized into four types: 1 If both three-spin and electron-microwave crossings occur during the rotor period, efficient DNP can take place; 2 If no three-spin crossing occurs, the electrons.

When in strong magnetic fields, they absorb specific wavelengths of microwave radiation as the nuclear spin axes #x27;flip#x27; to the opposite direction. A typical NMR spectrometer uses a fixed microwave frequency e. g., 90 MHz. The magnetic field, around 21 kiloGauss, is varied by careful control of the magnet current to give a record of. We use nominally forbidden electron-nuclear spin transitions in nitrogen-vacancy NV centers in diamond to demonstrate coherent manipulation of a nuclear spin ensemble using microwave fields at room temperature. We show that employing an off-axis magnetic field with a modest amplitude#92;approx 0.01 T at an angle with respect to the NV natural quantization axes is enough to tilt the. The spin#x27;s insensitivity to electric fields yields a solid-state qubit with record coherence times but also renders coupling to other quantum systems very challenging. Here, we describe how to generate a strong electric dipole gt; 100 D at microwave frequencies for the nuclear spin. This is achieved by applying a magnetic drive to the spin of.

The microwave-free technique for magnetic resonance spectroscopy is based on T1 relaxometry detection 7, 27, 28, 29, 30 and precise magnetic field tuning to bring the NV into resonance with the.. Electron Paramagnetic Resonance EPR, often called Electron Spin Resonance ESR, is a branch of spectroscopy in which electromagnetic radiation usually of microwave frequency is absorbed by molecules, ions, or atoms possessing electrons with unpaired spins, i.e.electronicspin S gt; 0.

Effects of Microwave Gating on Nuclear Spin Echoes in Dynamic Nuclear.
The nuclear spin polarization. We will present here our recent theoretical results on relaxation and decoherence processes of nuclear spin qubits in low-dimensional semiconductors and nanostructures [3]-[6] and on possibility of optical and microwave manipulation of nuclear spins in these systems. Optically pumped color centers in semiconductor powders can potentially induce high levels of nuclear spin polarization in surrounding solids or fluids at or near ambient conditions, but complications stemming from the random orientation of the particles and the presence of unpolarized paramagnetic defects hinder the flow of polarization beyond the defect#x27;s host material..

This leads to a prolongation of the nuclear coherence lifetime T21H. The increase in T21H leads to transient surges of the amplitudes of spin echoes. Conversely, transient slumps of spin echoes are observed when the microwave irradiation is switched back on, due to a shortening of nuclear coherence lifetimes..
Coherent Microwave Control of a Nuclear Spin Ensemble.
Nitrogen-vacancy centers possessing nuclear spins are promising candidates for a novel nuclear spin gyroscope. Preparation of a nuclear spin state is a crucial step to implement a sensor that utilizes a nuclear spin. In a low magnetic field, such a preparation utilizes population transfer, from polarized electronic spin to nuclear spin, using microwave pulses. The use of the narrowband.. Large-scale quantum computers must be built upon quantum bits that are both highly coherent and locally controllable. We demonstrate the quantum control of the electron and the nuclear spin of a single 31 P atom in silicon, using a continuous microwave magnetic field together with nanoscale electrostatic gates. The qubits are tuned into resonance with the microwave field by a local change in.
