| dc.description | The properties of Nb-doped YBa<sub>2</sub>Cu<sub>3</sub>O<sub>y</sub> ceramics obtained by thermolysis of the oxide or nitrate (Y, Ba, Cu) solution in ammonium nitrate melt were studied. For the composition YBa<sub>2</sub>Cu<sub>3-x</sub>Nb<sub>0.05</sub>O<sub>6.6</sub>, T<sub>c</sub> = 92 K and the transport critical current J<sub>c</sub> = 1000-4000 A cm<sup>-2</sup> were obtained. The magnetic flux profile was studied by a magneto-optic method at B = 290 G. Domains of size 200-600 mu m were found with magnetic critical current J<sub>c</sub><sup>m</sup> = 2 * 10<sup>4</sup> A cm<sup>-2</sup> at 77 K and 10<sup>5</sup> A cm<sup>-2</sup> at 11 K. |
