Electron-doped superconductivity at 40 K in the infinite-layer compound Sr(1-y)Nd(y)CuO2
Abstract
It is shown here that the isostructural compound Sr(1-y)Nd(y)CuO2, in which the substitution of neodymium for strontium adds electrons to the CuO2 planes, is superconducting at 40 K. The difference in dopant type seems to distinguish this superconductor from the superconductivity found in a multiphase sample of nominal composition Sr(1-y)Ba(y)CuO2 by Takano et al.
