摘要：
The properties of Nb-doped YBa2Cu3Oy ceramics obtained by thermolysis of the oxide or nitrate (Y, Ba, Cu) solution in ammonium nitrate melt were studied. For the composition YBa2Cu3-xNb0.05O6.6, T(c) = 92 K and the transport critical current J(c) = 1000-4000 A cm-2 were obtained. The magnetic flux profile was studied by a magneto-optic method at B = 290 G. Domains of size 200-600 mum were found with magnetic critical current J(c)m = 2 x 10(4) A cm-2 at 77 K and 10(5) cm-2 at 11 K.
