N2 - A new compound in the quaternary oxide system, Er-Ba-Cu-Pt-O, was discovered. Single crystals were grown using CuO as a flux in a platinum crucible by a slow cooling method. The platinum was supplied from the inner wall of the platinum crucible. Chemical analysis revealed the chemical composition of this compound to be ErBa1.03Cu0.77Pt0.46O4.34. The crystal system was found to be orthorhombic (space group Pcmn) with average unit cell dimensions a = 10.287(3) Å, b = 5.659(1) Å and c = 13.157 (3) Å. We propose the chemical formula of this compound as ErBa(Cu,Pt)O4. A large, but broad diamagnetic transition, which should come from the superconducting state, was observed below 80-90 K in single crystal aggregates.
