抄録

The Raman scattering at 1.16 eV laser excitation has been studied in ferromagnetic TDAE-C60 and compared to that in paramagnetic TDAE-C70. The shift of Hg and Ag modes in TDAE-C60 indicates transfer of one electron to C60 while the broadening of Hg modes is quite similar to metallic K3C60 meaning significant electron-phonon coupling of this Jahn - Teller vibrations. In TDAE-C70 the lines are narrow sugesting suppresed electron - phonon interaction and hence smaller polaronic effects. Below Tc of magnetic ordering the two-magnon excitations are not seen clearly however the low energy part of spectra shows somewhat increased intensity. Upon air-exposure of TDAE-C60 all Hg and Ag Raman modes disappear while a new band appears at 1848 cm-1.
