量子可果美反铁磁体ZnCu3(OH)6Cl 2

Quantum Kagome antiferromagnet ZnCu3(OH)6Cl2

Philippe Mendels, Fabrice Bert

摘要:

与S=1/2自旋的量子涨落增强相关的松散连接的戈薇晶格上反铁磁相互作用的挫败很久以前就被认为是稳定磁性物质新基态的关键点。直到最近,模型化合物Herbersmithite,ZnCu 3(OH)6Cl 2,一种结构完美的可果美反铁磁体,才被合成出来,并与理论进行了密切的比较。我们回顾和分类在过去几年中获得的各种实验结果,并强调一些悬而未决的问题。

英文摘要:

The frustration of antiferromagnetic interactions on the loosely connected kagome lattice associated to the enhancement of quantum fluctuations for S=1/2 spins was acknowledged long ago as a keypoint to stabilize novel ground states of magnetic matter. Only very recently, the model compound Herbersmithite, ZnCu3(OH)6Cl2, a structurally perfect kagome antiferromagnet, could be synthesized and enables a close comparison to theories. We review and classify various experimental results obtained over the past years and underline some of the pending issues.
