Sasakura, Y. Akagi, M. Tanaka, S. Tsukui, M. Adachi] New Pb-based 1222 cuprates containing phosphorus have been synthesized in the (Pb,P)Sr2(Eu,Ce,Sr)2 Cu2Oz system. From X-ray powder diffraction study, almost the single 1222 phase samples are found to be obtained in a considerable wide composition area of 0.3≤x≤1.2 for the nominal composition of (Pb0.75P0.25)Sr2(Eu1.9−x CexSr0.1) Cu2Oz. The crystal structure for each sample has a tetragonal symmetry and the typical lattice parameters are a=0.3851nm and c=2.922nm. After annealing under 143atm O2 atmosphere at 400 °C, a sample with x=0.3 among the almost-single phase samples shows an onset of resistivity-drop at the highest temperature of about 22K and zero-resistivity at the highest temperature of about 12K, then this sample also shows an onset of diamagnetic signal at about 20K. These phenomena are found to originate from superconductivity of the new 1222 phase.
