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 ...
متن کاملElectron spin resonance spectrum of a new anthraquinone aglycone (Nodosin).
The Electron Spin Resonance study of 1,3,5,8-tetrahydroxy 2,7-dimethyl anthraquinone known as Nodosin has been carried out at room temperature and at X-band. The compound gives a norrow ESR line. The measurements of lineshape, linewidth and g-value have been made. A theoretical computation of dipolar width as well as narrowing due to exchange has been carried out with the help of KUBO and TOMIT...

متن کاملElectron Spin Resonance
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...
متن کاملElectron Spin 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...
