通过测量低温红外区磁场下的光学反射率、磁线性二色性和磁圆二色性光谱，研究了磁有序态CeSb的电子结构。光学电导率谱以及反射率谱随复杂的磁相图发生显着变化，并给出了有序态电子结构的详细信息。由于周期性磁结构的出现，有序态的光谱不能仅用能带折叠来解释。通过与计算的电导谱进行比较，我们发现不仅Ce4 f –Sb5 p 混合而且Ce5 d –Sb5 p 混合都主要在有序态下进行。
The electronic structure of CeSb in the magnetically ordered states is examined by measuring the optical reflectivity, the magnetic linear dichroism and the magnetic circular dichroism spectra at low temperatures under magnetic fields in the infrared region. The optical conductivity spectrum, as well as the reflectivity spectrum changes significantly with the complex magnetic phase diagram, and gives detailed information of electronic structures in the ordered states. The spectra in the ordered states cannot be explained only by the energy band folding due to the appearance of the periodic magnetic structure. By comparing with the calculated optical conductivity spectra, we found that not only the Ce4 f –Sb5 p mixing but also the Ce5 d –Sb5 p mixing mainly works in the ordered states.
