Abstract:
Electron spin resonance in a multilayer graphene–polystyrene composite has been studied as dependent on the temperature and magnetic field. The observed $g$-factor of 2.003 was independent of the temperature and fell in the interval ($g$ = 2.0022–2.0035) characteristic of the free electron of carbon. This behavior of the $g$-factor excludes the appearance of internal magnetic field in the composite.
