✦ Synopsis

We have clariÿed carrier spin relaxation process in multi walled carbon nanotubes (MWCNT) fabricated by DC arc discharge and studied the fundamental transport mechanism in MWCNT by means of electron spin resonance (ESR) in order to discuss on the transport properties in the MWCNT. The g-value and the line width for the ESR signal are gradually increased after thermal annealing. This can be explained by a conduction electron system in the MWCNT.
