Abstract

New charge-transfer salts (EDO-TTFI₂)₂M(mnt)₂ (M = Ni, Pt) are the first organic metals with strong ferromagnetic interactions. These salts consist of one-dimensional chains of EDO-TTFI₂ donors and M(mnt)₂ acceptors aligned in parallel to each other. The metallic conductivity is due to the one dimensional chain of EDO-TTFI₂, and a metal-insulator transition occurs at about 90 K. Localized spins of M(mnt)₂ behave as a one-dimensional ferromagnet, which interact with conduction electrons. The origin of the ferromagnetic interactions are orthogonality of the molecular orbitals of M(mnt)₂ and spin polarization effect which is explained by McConnell's first model.
