Study of Electron Spin Lifetime of Conducting Carbon Nanomaterials

Balint Nafradi, Mohammad Choucair and Laszlo Forro

Abstract

The usefulness of electron spins in quantum information technologies such as spintronics or quantum computation is determined by the spin-lattice (T1) and spinspin (T2) relaxation times. These relaxation times should be long relative to the characteristic times required for spin control in order to allow for controlled information manipulation. Despite the central importance of T1 and T2 in modern information technologies, direct experimental access to these quantities is scarce. Electron spin resonance (ESR) spectroscopy is one of the few-experimental methods, offering direct access to both T1 and T2 of electrons. In this chapter, we present recent advancements in pulsed and continuous wave ESR spectroscopy of conducting carbon nanomaterials that have emerged with the potential for practical applications.
