The development of multilayer mirrors for continual use around the K-absorption edge of carbon (4.4 nm) has been begun. CoO, SiO, and BN are found to be suitable for multilayer mirrors based on theoretical calculations for wavelengths around the carbon K-absorption edge region. X-ray reflectivity curves with Cu X rays of the fabricated CoO/SiO multilayers have sharp Bragg peaks and the layer structures evaluated from TEM observations are uniform. On the other hand, the Bragg peaks of CoO/BN multilayers split and aggregated CoO is observed. To improve the CoO layer structure, CrO was mixed into CoO. The mixed oxide layer structure in the Mix/BN multilayer (Mix = CoO + CrO) is relatively uniform and the Bragg peaks do not split.
