The fields of molecular conductors and molecular magnets are very active and have long history in Japan. This research projects aimed to cultivate new research field between the field of molecular conductors and that of molecular magnets by the tight cooperation between physicists and chemists in these fields. During the term of this project, we have developed various magnetic organic superconductors exhibiting unprecedented electro-magnetic properties by combining conduction function of π donor molecules and magnetic function of anions. Typical examples are the first antiferro-magnetic organic superconductor κ-(BETS)_2FeBr_4 and λ-(BETS)_2FeCl_4 exhibiting field-induced superconductivity. We have also developed chiral molecular magnets with fairly high T_<c'> which are expected to show a salient bi-functional magneto-optical properties such as magneto-chiral dichroism. Through these works, various multi-functional magnetic molecular systems, where the electron spins play an essential role have been discovered.

分子导体和分子磁体领域在日本非常活跃，有着悠久的历史。本研究项目旨在通过分子导体和分子磁体领域的物理学家和化学家的紧密合作，培育分子导体和分子磁体领域之间的新的研究领域。在本项目期间，我们结合π给体分子的传导功能和阴离子的磁性功能，开发了多种具有前所未有的电磁性能的磁性有机超导体。典型的例子是第一个反铁磁性有机超导体κ-(BETS)_2FeBr_4和λ-(BETS)_2FeCl_4表现出场致超导性。我们还开发了具有相当高T_<c'>的手性分子磁体，有望表现出显著的磁手二色性等双功能磁光性质。通过这些工作，发现了各种多功能磁性分子体系，其中电子自旋起着重要作用。
