MOLECULAR MAGNETS BASED ON CHARGE-TRANSFER COMPLEXES

We investigated two classes of organic charge transfer complexes in th e TTF family and related materials, in order to aim at the development of novel magnetic systems. The first one is the complexes with transi tion metal d-electrons having localized magnetic moments, where the pi -electrons in organic donors play an important role in the exchange in teraction mechanism between the Localized magnetic moments of d-electr ons. The second class is obtained on the basis of the localized magnet ic moments of pi-electrons, where the on-site Coulomb interaction in o rganic donors overwhelms the transfer integral.
