本文研究了非传导电子（-）杂化与非常规反铁磁有序态转变温度之间的关系。压力对晶体结构和电子结构的影响已被测量使用X射线衍射和共振X射线发射光谱在Ce吸收边在金刚石压砧单元。我们的结果表明，晶格间距意味着一些相关的消失。然而，所测得的价态的分析表明，只有一个弱的相关性与相应的临界消失的AFM命令内的实验误差。我们的结果可以解释的情况下，基于Kondo-Heisenberg模型超出了传统的Doniach相图。
The correlation between the-conduction electron (-) hybridization and the transition temperatureinto the unconventional antiferromagnetically (AFM) ordered state inhas been investigated. The impact of pressure on the crystal structure and the electronic structure has been measured using x-ray diffraction and resonant x-ray emission spectroscopy at the Ceabsorption edge in a diamond anvil cell. Our results show that the lattice spacings imply some correlation with the disappearance of. Analyses of the measured valence states, however, show only a weak correlation with the corresponding critical disappearance of the AFM order within experimental errors. Our results may be explained by a scenario based on the Kondo-Heisenberg model beyond the conventional Doniach phase diagram.
