Novel Experimental Approach to Obtain the Oxygen-Deficient LaBaCaCu3Oy Superconductor Compound


This work presents a novel approach based on the nitrate decomposition method for the preparation the oxygen-deficient LaBaCaCu3Oy (La1113) compound. The XRD results reveal the presence of the triple perovskite structure LaBaCaCu3Oy as a dominant phase crystallizing in the tetragonal system with the space group P4/mmm. The SEM observation shows a low porosity and EDAX data indicates the presence of the basic elements of the phase. The superconducting character of the compound is confirmed by AC susceptibility measurements with Tc = 63 K even if the samples are not treated under oxygen atmosphere.
