摘要

我们结合密度泛函理论（DFT）计算，进行了角度分辨光发射光谱（ARPES）测量，研究了一系列反铁磁（AFM）转变后铋铈电子结构的演变。除了之前通过输运研究得知的两种转变之外，我们还发现了一种新的 AFM 转变的证据。我们证明在（+-+-）有序相中出现了一个额外的狄拉克态，在（++--）有序相中出现了非常规表面态对的转变。这修正了这种有趣材料的相图，现在在零磁场下的 TN 以下有三种不同的 AFM 状态，而不是以前认为的两种。

Unexpected changes in the band structure within AFM1 state of CeBi

We perform angle-resolved photoemission spectroscopy (ARPES) measurements in conjunction with density functional theory (DFT) calculations to investigate the evolution of the electronic structure of CeBi upon a series of antiferromagnetic (AFM) transitions. We find evidence for a new AFM transition in addition to two previously known from transport studies. We demonstrate the development of an additional Dirac state in the (+-+-) ordered phase and a transformation of unconventional surface-state pairs in the (++--) ordered phase. This revises the phase diagram of this intriguing material, where there are now three distinct AFM states below TN in zero magnetic field instead of two as it was previously thought.
