Synthesis and Characterization of Low Dimensional Magnetic and Conductive Systems

决定绝缘固体中磁性行为的结构和电子因素有待研究。重点讨论了这些材料中影响磁各向异性的因素。将强调使用电子顺磁共振(EPR)以及磁化和磁化率研究来探测铜(II)卤化物中的磁各向异性。磁-结构关联的描述将被用作获得各种低维系统的基础。将包括用于验证霍尔丹猜想的S=1链，具有非导电磁体潜力的铁磁链，以及层-钙钛矿系统。此外，还将研究一组具有一维导体势能的混合价链。

The structural and electronic factors which determine magnetic behavior in insulating solids are to be investigated. The emphasis will be on those factors which influence the magnetic anisotropy in these materials. The use of electron paramagnetic resonance (EPR) as well as magnetization and magnetic susceptibility studies to probe magnetic anisotropies in copper (II) halides will be stressed. The delineation of magneto- structural correlations will be used as basis to obtain a wide variety of low dimensional systems. included will be S=1 chains to test the Haldane conjecture, ferromagnetic chains with potential as non-conducting magnets, and layer-perovskite systems. In addition, a set a mixed valence chains with potential as one dimensional conductors will be investigated.
