High gas pressure up to 11 kbar has been applied for the synthesis and single crystal growth of Hg-based superconductors and one-dimensional A{sub 1{minus}x}CuO{sub 2} cuprates. The authors have investigated the influence of Re, Sr and Pb substitutions and oxygen content on the magnetic flux-pinning properties of single crystals of Hg-based superconductors. The best results have been obtained for Sr and Pb substituted Hg1223 single crystals. Susceptibility, neutron scattering, and torque investigations have been performed on Ca{sub 0.83}CuO{sub 2}, Sr{sub 0.73}CuO{sub 2} and Ba{sub 0.67}CuO{sub 2} compounds containing CuO{sub 2} infinite chains separated by Ca, Sr or Ba layers.
