Spin dynamics and charge transfer in C60· 2ferrocene studied by electron spin resonance

Abstract Electron spin resonance (ESR) has been applied to study spin dynamics and charge transfer interactions in C60(Fe(C5H5)2)2. A low concentration of C 60 − spins is derived by ESR, suggesting the presence of weak charge transfer between C60 and ferrocene. The C 60 − ESR spectra display an appreciable anisotropy at T C 60 − ESR.
