The development of highly reflective multilayer mirrors for use in the wavelength region around 6 nm has made it possible to use a multilayer‐coated Schwarzschild objective for micro‐x‐ray photoemission spectroscopy. For this purpose, Co x Cr 1− x /C and W/C multilayers were fabricated by magnetron sputtering and the soft x‐ray reflectivities were measured. The peak reflectivity of the Cr/C multilayer was found to be the highest with ∼18.9% at a wavelength of 6.42 nm and an incident angle of 88°. It is believed that a Cr/C multilayer will provide sufficient performance for use on a Schwarzschild mirror for x‐ray photoemission spectroscopy using 6 nm x‐rays.
