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 کاملHigh-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 ...

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...
