The DC Josephson effect between grains in YBa2Cua07 and TI2CaBa2Cu20e sinters was investigated. DC SQUID operation was detected in two geometries up to T = 86 K and T = 101 K respectively. The results are consistent with the assumption that the grain boundaries are S-N-S or S-S'-S junctions and that

Parent Bi2CaSr2Cu2Os+6 superconductor was doped with oxygen by annealing powder sample at 500 Β°C in the flowing oxygen atmosphere with intermittent grinding. The amount of amorphous phase and insulating layer found on the sanh~le surface was increased with more oxygen doping. As a consequence, the
Well developed single crystals of the mercury compound HgBa2Ca2Cu3OS+d have been obtained in single step synthesis under normal pressure conditions. Samples in the submillimeter range give a sizeable diamagnetic signal which allowed a systematic study of the magnetization anisotropy both before and
