作为URu $_2$ Si $_2$隐序相候选的自旋双稳态

Spin nematic state as a candidate of the hidden order phase of URu$_2$Si$_2$

Satoshi Fujimoto

摘要:

基于最近在URu $_2$ Si $_2$的隐序相中发现的四重对称破缺[R. Okazaki等人,Science { \bf 331},439(2011)]中,我们检查了作为隐藏顺序相的可能候选者的自旋双稳态的情形。我们证明,该方案自然地解释了大多数的实验观察,而且,成功地再现了上述实验中检测到的自旋各向异性的温度依赖性在半定量的方式。这一结果为自旋有序的实现提供了有力的证据。

英文摘要:

Motivated by the recent discovery of broken four-fold symmetry in the hidden order phase of URu$_2$Si$_2$[R. Okazaki et al., Science {\bf 331}, 439 (2011)], we examine a scenario of a spin nematic state as a possible candidate of the hidden order phase. We demonstrate that the scenario naturally explains most of experimental observations, and furthermore, reproduces successfully the temperature dependence of the spin anisotropy detected by the above-mentioned experiment in a semi-quantitative way. This result provides strong evidence for the realization of the spin nematic order.
