The vast majority of magnetic resonance imaging and spectroscopic investigations make use of nuclear magnetic resonance (NMR), exploiting the interactions of atomic nuclei with applied static and radiofrequency magnetic fields. Nevertheless, there exists another important “flavour” of magnetic resonance, called Electron Spin Resonance (ESR) – or, interchangeably, Electron Paramagnetic Resonance...

Quantum theory tells us electrons have certain properties such as spin. Any type of angular momentum, including spin, can be coupled with a magnetic field. Such a coupling, along with microwave spectroscopy, can be used to study specific attributes of certain types of materials. This phenomenon is exploited in electron spin resonance (ESR) microwave spectroscopy. Among the materials that can be...

We report an experimental demonstration of generating electron spin polarization with linearly polarized light in a (110) GaAs quantum well. A detailed frequency-domain pump-probe study shows that the dynamic nuclear spin polarization arising from the oriented electron spins results in a strong dependence of the electron spin splitting on the photon energy and intensity of the linearly polarize...

To order the complete compilation report, use: ADA398590 The component part is provided here to allow users access to individually authored sections f proceedings, annals, symposia, etc. However, the component should be considered within [he context of the overall compilation report and not as a stand-alone technical report. Multilayered structures of a-Si/SiO 2 sequences were deposited using a...

in this study, silver nanoparticles were synthesized by chemical reduction method at different concentrations of ag colloid in the range of 500-16000 ppm. nanoparticles were deposited by spin coating method on pre-etched glass and si substrates. structural, optical and electrical properties of the samples were studied using scanning electron microscopy equipped with edax, uv-vis spectrophotomet...
