Abstract
Abstract In this research, we seek a new superconducting candidate LaAlYbCuO based on the need to improve upon the lanthanum cuprates framework. LaAlYbCuO high temperature superconductor was prepared by standard solid-state reaction. The characterization was done by the X-ray powder diffraction technique, Scanning Electron Microscopy (SEM) and Rutherford Backscattering Spectrometry (RBS). The analysis of the images was done using Match, Vesta, SRIM, CERN-Root, OMDAQ and Gwydion software. The XRD refinements show that LAYbCO has orthorhombic structure with unit cell as a = 3.865 A, b = 3.865 A, c = 19.887 A. The specimen had theta correction of 0.19891°. The ratio of electron to phonon production in LAYbCO is approximately 999:1. However, this does not rule-out the possibility of electron-phonon interaction. The elemental composition of LAYbCO is given as La1.35Al3.97 Yb6.80Cu6.80O15 at Q-factor – 0.033, Chi-square – 0.6057 and dMax – 173. The new LAYbCO framework showed high chemical homogeneity. It was discovered that natural inclination of the atomic structure is quite important for structural interpretations.
