Superconductivity at 52.5 K in the Lanthanum-Barium-Copper-Oxide System

Abstract

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 CuO 4- y Possible causes for the high-temperature superconductivity are discussed.
