SINGLE-CRYSTALS OF HG-12(N-1)N AND INFINITE-LAYER CACUO2 OBTAINED AT GAS-PRESSURE P=10KBAR

Single crystals of Hg1-xPbxBa2Can-1CunO2n+2+delta (X=0, 0.2, 0.5; n=2, 3,4,5) and infinite layer CaCuO2 compounds have been grown using a hig h gas pressure. Resistivity measurements have been performed in fields up to 10 T. The Hg0.8Pb0.2-1234 single crystals of a size up to 0.5x0 .5 mm(2) have a T-c onset of 130 K. Single crystals of CaCuO2 of a siz e up to 2x1 mm(2) have a T-c onset between 70 and 100 K. X-ray structu ral refinements have been performed on the CaCuO2 and HgPb-12(n-1)n si ngle crystals.
