Precise determination of oxygen content in SmBa2Cu3O7-δ thin film samples using x-ray diffraction
Abstract
The superconducting properties of SmBa2Cu3O7-δ (SmBCO) thin films are predominantly influenced by the oxygen deficiency δ. Yet, the established methods to determine δ such as iodometric titration or thermogravimetry cannot be applied to thin films due to their very small volume.
Therefore, an alternative way to determine δ for SmBCO thin film samples using X-ray diffraction (XRD) is presented. Main point of this analysis is the structural relationship between the a, b and c lattice parameters and δ. A linear relationship between c and δ is found in SmBCO powder samples for both the orthorhombic and tetragonal phases.
Furthermore, an attempt is made to quantify the chemical composition using Time-of-Flight Secondary Ion Mass Spectrometry (ToF-SIMS). This attempt was inconclusive because of drastically changing ion yields due to δ influencing the valence state of the analyzed ions.
The found crystal structural relationship gathered from the powder samples is applied to thin film samples. Thereby, it becomes clear that thermal strain is affecting the crystal structure of the thin films. A simple correction model is used to correct for thermal strain and a good match between powder, literature and thin film data is achieved and thus a non-destructive way for the determination of δ using XRD.
