9803074Kauzlaric本项目旨在合成和表征新型过渡离子金属烟酸和烟碱氧化物化合物。目标有三个：了解和改进在钙-铝-锑(Cal4AISbl I)结构类型的含锰化合物等材料中发现的巨磁电阻(CMR)效应；合成三元过渡金属锌相并研究其磁性和电子性质；以及合成新的层状磷灰石氧化物，特别是含铜和钛的化合物。学生将接受固态化学合成和表征技术方面的培训。预计这些新类别的化合物将表现出有趣的磁性和超导行为，可能用于设备。技术影响的例子可能包括用于磁读取头设备的巨大磁阻材料，以及用于电子和通信的超导材料。

9803074KauzlarichThis project aims to synthesize and characterize novel transitiion metal pnictide and pnictide oxide compounds. The goals are threefold: to understand and improve on the colossal magnetoresisyance (CMR) effect found in materials such as the manganese containing compounds of the calcium-aluminum-antimony (Cal4AISbl I) structure type; to synthesize ternary transiton metal Zintl phases and study their magnetic and electronic properties; and to synthesize new layered pnictide oxides with particular emphasis on the copper and titanium containing compounds. Students will be trained in solid state chemical synthesis and characterization techniques.%%%It is expected that these new classes of compounds will exhibit interesting magnetic and superconducting behavior for possible use in devices. Examples of technological impact may include colossal magnetoresistance materials for magnetic read-head devices, and superconducting materials for electronics and communications.***
