The compound Ho/sub 1/Ba/sub 2/Cu/sub 3/O/sub 9-//sub delta/ has been found to be a high T/sub c/ superconductor. The onset of the superconducting transition is 88 K with zero resistance achieved at 87 K. The x-ray diffraction spectrum of this material shows it to be a single-phase perovskite similar to the Y/sub 1/Ba/sub 2/Cu/sub 3/O/sub 9-//sub delta/ compound but different from the K/sub 2/NiF/sub 4/ perovskite which is believed to be the superconducting phase for the La/sub 2(1-//sub x//sub )/ Ba/sub 2//sub x/CuO/sub 4-//sub delta/ system. Possible oxygen deficiencies in several of the unit cell planes are discussed. The room-temperature resistance, the superconducting onset temperature, and the emergence of the single phase all depend upon the sample preparation firing conditions.
