Abstract
We prepared multilayer taped from (Tl,Pb)-1223 thick films electrophor etically deposited on silver tapes. A multilayer tape was rolled in th e transverse direction, pressed and sintered. The transport current wa s 33 A at 77 K and 80 A at 30 K, corresponding to a critical current d ensity of about 10(4) A cm(-2) at 77 K. In a magnetic field of 0.1 T t he critical current density decreased by a factor of 20 and remained n early constant at higher fields. The critical current density derived from magnetization data was 7 x 10(5) A cm(-2) at 10 K and 8 x 10(4) A cm(-2) at 77 K.
