摘　　要：概述了分子磁交换的机理研究及其进展。介绍了直接交换、超交换和双交换三种作用机理及基于自旋密度分析的自旋极化和自旋离域作用机制 ,并对今后分子磁性的理论研究作了展望。The magnetic exchange interaction for molecular systems is outlined. Three theoretical models of magnetic exchange mechanism for molecular systems, direct exchange, super-exchange and double exchange interactions are reviewed. Also based on spin population analysis, the spin delocalization and spin polarization mechanisms are introduced. Several typical magnetic molecular systems are analyzed from the point of view of the mechanisms mentioned above. Finally, the prospect on molecular magnetism theory is presented.
