Pulsed electron spin resonance of an organic microcrystal by dispersive readout

MAGNETISATION AND ELECTRON SPIN RESONANCE STUDIES OF TETRAHEDRAL AMORPHOUS CARBON

The magnetisation and electron spin resonance (ESR) spectrum of two specimens of tetrahedral amorphous carbon (ta-C), deposited from a filtered cathodic arc, were measured over a wide temperature range. The magnetisation was found to consist of superparamagnetic, paramagnetic and diamagnetic contributions. The superparamagnetic contribution resembled that recently found in carbon prepared from ...

High-power 95 GHz pulsed electron spin resonance spectrometer

High-field/high-frequency electron spin resonance ~ESR! offers improved sensitivity and resolution compared to ESR at conventional fields and frequencies. However, most high-field/high-frequency ESR spectrometers suffer from limited mm-wave power, thereby requiring long mm-wave pulses. This precludes their use when relaxation times are short, e.g., in fluid samples. Low mm-wave power is also a ...

Electron spin manipulation and readout through an optical fiber

The electron spin of nitrogen--vacancy (NV) centers in diamond offers a solid-state quantum bit and enables high-precision magnetic-field sensing on the nanoscale. Implementation of these approaches in a fiber format would offer unique opportunities for a broad range of technologies ranging from quantum information to neuroscience and bioimaging. Here, we demonstrate an ultracompact fiber-optic...

Measurements of Dynamics , Structure , and Flexibility of Macromolecules by Pulsed Electron Spin Resonance

An Electron Spin Resonance Study of Neoplasms.

Twenty-nine types of mouse tumor and two normal mouse tissues were examined in the frozen state by electron spin resonance spectroscopy, and the redox states of some components were characterized. Intracellular organelles of mouse hepatoma and of normal mouse liver were separated by differential centrifugation and examined by elec tron spin resonance spectroscopy. The major difference between t...
