Abstract

High temperature superconducting LaBa2Cu3O7−δ has been prepared by ceramic and nitrate methods to understand the influence of preparation conditions on superconductivity. The characterization was carried out by X-ray diffraction and magnetic susceptibility measurements.T c onset was observed at 88 K. Meissner effect has been observed above the liquid nitrogen temperature.
