Possible RT superconductivity from Pb3CO5-Ag2O (PACO) system

Some interesting results that could be eventualy explained as coming from superconductivity (SC) in Pb3CO5-Ag2O (PACO) szstem are reported. Samples prepared at 340-350 oC in combined CO2-O2 atmosphere exhibit low resistance states at room temperature (RT) with resistivity three orders of magnitude lower than that of silver. In addition, characteristic treshold current density dependence of electric resistance together with the DC susceptibility data obtained on balance support the idea of superconductivity in PCAO system.
