摘要:

对URu $_2$ Si $_2$的微分弹性电阻的测量表明,与17 K隐序相变有关的涨落具有一个非线性分量.从上方接近“隐藏顺序”相变时,磁化率突然改变符号,表明虽然隐藏顺序相位具有磁化率分量,但它破坏了额外的对称性。

英文摘要:

Measurements of the differential elastoresistance of URu$_2$Si$_2$ reveal that the fluctuations associated with the 17 K Hidden Order phase transition have a nematic component. Approaching the "Hidden Order" phase transition from above, the nematic susceptibility abruptly changes sign, indicating that while the Hidden Order phase has a nematic component, it breaks additional symmetries.
