Theoretical Studies on Electronic States of Rh-C60. Possibility of a Room-temperature Organic Ferromagnet
Abstract
A possible mechanism for a ferromagnetic interaction in the rhombic (Rh) formof C60 (Rh-C60) is suggested on the basis of theoretical studies in relation to cage distortionof the C60 unit in the polymerized 2D-plane. Band structure calculations on Rh-C60 showthat cage distortion leads to competition between diamagnetic and ferromagnetic states,which give rise to the possibility of thermally populating the ferromagnetic state.
