X-ray absorption spectroscopy data of SrFe1-xCoxO3-δ (x = 0, 0.2, 0.4, 0.6, 0.8) - K-edge of iron and K-edge of cobalt

The dataset consists of two catalogs, containing X-ray absorption spectroscopy (XAS) data of SrFe1-xCoxO3-δ (x = 0, 0.2, 0.4, 0.6, 0.8) perovskites measured at K-edge of iron (7.112 keV) and cobalt (7.709 keV). The measurements were conducted at the SOLARIS National Synchrotron Radiation Centre (Poland) at the ASTRA beamline under ambient atmosphere. The dataset contains transmission mode measurements collected on the ASTRA beamline. The data for each sample is presented as the ratio I0/I1, while reference data (from Fe or Co metal foils) is given as the ratio I1/I2. The intensities I0, I1, and I2 in transmission XAS measurements can be described as follows: - I0 is the intensity of the incident X-ray beam before it reaches the sample,- I1 is the intensity of the X-ray beam after passing through the sample,- I2 is the intensity of the X-ray beam after passing through the reference material (e.g., Fe or Co metal foil).
The names of files indicate the data they consist:- the measured absorption edge (K-Fe and K-Co, indicating K-edge of iron and cobalt, respectively),- the material studied (SFO, SFC2, SFC4, SFC6, and SFC8, signifying SrFe1-xCoxO3-δ containing 0, 20, 40, 60, and 80% of cobalt in the B-site, respectively).
