摘要:

(Per)2[Au(mnt)2]在压力下的角相关磁电阻效应揭示了与晶体学参数相关的几何效应。压力抑制了材料的基态电荷密度波,在金属态同时出现几何和轨道量子干涉效应。通过磁场依赖性和取向,轨道和几何效应被独立地识别。我们比较的结果从(Per)2[Au(mnt)2]与以前的研究众所周知的Bechgaard盐。

英文摘要:

The angular dependent magnetoresistance of (Per)2[Au(mnt)2] under pressure has revealed geometrical effects associated with the crystallographic parameters. Pressure suppresses the charge density wave ground state of the material, and in the metallic state both geometrical and orbital quantum interference effects appear. Through magnetic field dependence and orientation, the orbital and geometrical effects are independently identified. We compare the results from (Per)2[Au(mnt)2] with previous studies of the well-known Bechgaard salts.
