[background technology]:
Organic magnet is the frontier branch of science of a multidisciplinary intersection; It relates to subjects such as organic and inorganic, organo-metallic, polymkeric substance, physical chemistry, Condensed Matter Physics, belongs to main research and has magnetic, photoconduction, electricity and the design of the molecular system of specific physical character, synthetic and application such as lead
[1]Emerging research field---the molecular solid (Molecular solid) of multidisciplinary intersection.For a long time, people think that an organic/inorganic substance just has above these character, and organism then is considered to diamagnetic material or electrical insulator.Up to recently, all proved in theoretical and the test some special organic materials through overdoping or with other organic or inorganic ionic bond after, can show magnetic or change conductor into even superconductor.Phase at the beginning of the sixties in last century, MeConnell
[2]Proposition is encouraging people to make unremitting effort for seeking such system based on the theory prophesy that the ferro-magnetic of molecular system possibly exist.At present, this field relates to organic semiconductor, organic photoconductor, organic conductor and superconductor, conductive polymers, organic non linear optical material, new-type functional material such as Organic Ferromagnet and relevant electronic processes.Compare with other materials research, though the research of Organic Ferromagnet is started late, researchdevelopment has in recent years fully shown the development potentiality in this field.
