| Outline of Final Research Achievements |
In this research, we aimed to apply inelastic neutron scattering (INS) measurement to studies on dynamics in the organic conductors using a chopper spectrometer installed at J-PARC.
We succeeded observation of a full picture of the phonon spectrum in an organic conductor, beta'-(BEDT-TTF)2ICl2, by INS for the first time. It was found there that a low-energy optical mode is strongly coupled with the charge and spin degrees of freedom. We also tried direct observation of magnetic excitation in this material. However, we have not yet succeeded its observation because the magnetic intensity rapidly decreases due to the spin widely distributed on a molecule.
