摘要: Abstract We report here results from a study of superconductivity in the Sm 1.85 (Ce 0.15−x Th x )CuO 4−y system. observe resistive superconducting transitions for all values x, with transition midpoints ranging 19.3 K =0 to 1.9 =0.15. This is first reported observation compound 0.15 CuO . Magnetic susceptibility measurements performed on this verify presence superconductivity. Additionally, electrical resistivity done under pressure show decrease T c at rate dT /dP=-0.043 K/kbar.
