Superconductivity at 52.5 k in the lanthanum-barium-copper-oxide system.
A superconducting transition with an onset temperature of 52.5 K has been observed under hydrostatic pressure in compounds with nominal compositions given by (La(0.9)Ba(0.1))(2) CuO4-Y. Possible causes for the high-temperature superconductivity are discussed.
