The critical current and flux pinning properties of melt grown YBa2Cu3OT\_6 bulk material were investigated by transport measurements and V-I characteristics. A Jยข of 16 000 A cm -2 in zero field and 3000 A cm -2 in 1 T at 77 K was obtained using a criterion of 3.3 I~V cm-~. No features of granulari
Y1Ba2Cu307\_x and Bi2Sr2CalCu208+ x Ag sheathed high Tc superconductor wires have been prepared using the powder in tube technique. Characterization of wire specimens was performed mainly by measuring critical current densities at 77 K and 4.2 K, as well as by a.c. susceptibility measurements. Where
