%0 Journal Article %J Journal of Non-Crystalline Solids %D 2008 %T Spin dynamics and charge transfer in C60 · 2ferrocene studied by electron spin resonance %A Guskos, N. %A Soldatov, A.G. %A Zolnierkiewicz, G. %A V. Likodimos %A Glenis, S. %X 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 C60- spins is derived by ESR, suggesting the presence of weak charge transfer between C60 and ferrocene. The C60- ESR spectra display an appreciable anisotropy at T < 40 K reflecting molecular rotation freezing, while their low temperature variation (T < 10 K) implies development of antiferromagnetic spin-spin interactions. At high temperatures, the narrow ESR line of C120O- impurity spins inhibits observation of a C60- ESR. © 2008 Elsevier B.V.
