论文摘要
结合了第一个原理密度功能计算和Moriya的自洽重新归一化理论，我们解释了最近报道的在单轴线紧张的SR $ _2 $ _2 $ ruo $ _4 $ _4 $以外的有序磁状态的违反直觉外观。我们表明，菌株削弱了量子自旋波动，这比磁性趋势更强烈地破坏了静态顺序。自旋波动与磁性稳定能量的不同降低速率可促进临界应变以外的静态磁顺序的发作。
Combining first principle density functional calculations and Moriya's self-consistent renormalization theory, we explain the recently reported counterintuitive appearance of an ordered magnetic state in uniaxially strained Sr$_2$RuO$_4$ beyond the Lifshits transition. We show that strain weakens the quantum spin fluctuations, which destroy the static order, more strongly than the tendency to magnetism. A different rate of decrease of the spin fluctuations vs. magnetic stabilization energy promotes the onset of a static magnetic order beyond a critical strain.
