Pulsed magnetic field generation suited for low-field unilateral nuclear magnetic resonance systems

open access: yesAIP Advances, 2018
Pulsed magnetic fields can be used to provide instantaneous localized magnetic field variations. In presence of static fields, pulsed field variations are often used to apply torques and in-effect to measure behavior of magnetic moments in different ...

Nanomechanical Analog of a Laser: Amplification of Mechanical Oscillations by Stimulated Zeeman Transitions [PDF]

open access: yes, 2003
We propose a magnetomechanical device that exhibits many properties of a laser. The device is formed by a nanocantilever and dynamically polarized paramagnetic nuclei of a solid sample in a strong external magnetic field.

Nanoscale Fourier-Transform Magnetic Resonance Imaging

open access: yesPhysical Review X, 2013
We report a method for nanometer-scale pulsed nuclear magnetic resonance imaging and spectroscopy. Periodic radio-frequency pulses are used to create temporal correlations in the statistical polarization of a solid organic sample.

The Gyrotrons as Promising Radiation Sources for THz Sensing and Imaging

open access: yesApplied Sciences, 2020
The gyrotrons are powerful sources of coherent radiation that can operate in both pulsed and CW (continuous wave) regimes. Their recent advancement toward higher frequencies reached the terahertz (THz) region and opened the road to many new applications ...

Comparative evaluation of the micelle formation process of phospolipids of rapeseed and sunflower lecithines in nonpolar solvents

open access: yesНовые технологии, 2019
It is known that the ability of phospholipids in plant lecithins to micelle formation in solutions of non-polar solvents depends on their chemical composition.

Aminoxyl Radicals of B/P Frustrated Lewis Pairs: Refinement of the Spin-Hamiltonian Parameters by Field- and Temperature-Dependent Pulsed EPR Spectroscopy. [PDF]

open access: yesPLoS ONE, 2016
Q-band and X-band pulsed electron paramagnetic resonance spectroscopic methods (EPR) in the solid state were employed to refine the parameters characterizing the anisotropic interactions present in six nitroxide radicals prepared by N,N addition of NO to

Nuclear spin coherence in a quantum wire

open access: yes, 2009
We have observed millisecond-long coherent evolution of nuclear spins in a quantum wire at 1.2 K. Local, all-electrical manipulation of nuclear spins is achieved by dynamic nuclear polarization in the breakdown regime of the Integer Quantum Hall Effect ...
