N2 - Single-phase superconducting YBa2Cu4Oy has been synthesized at 780–790°C under one atmosphere oxygen pressure with the sol-gel powder precursor method. The precursor was derived from citrate metal-ion complexes dispersed in a solvent mixtures of ethylene glycol and water. From X-ray diffraction analysis, the material was found to be single phase. The superconducting transition observed in terms of complex susceptibility showed that the onset temperature of superconducting transition is 87.8 K and the transition width (10–90%) is 4.5 K.
