Abstract
A low-cost electrodeposition (ED) method is tested for fabricating high-temperature superconducting film. The development of biaxially textured electrodeposited (TlBi)0.9Sr1.6Ba0.4Ca2Cu 3Ag0.2Ox (TBSBCCO-Ag) films on Ag-coated, single-crystal substrates is reported. Pole-figure measurements of electrodeposited TBSBCCO-Ag film on 300 Å Ag/LaAlO3 clearly show strong biaxial texturing. The omega scan and phi scan indicate the full width at half-maximum of only 0.9 and 1.2°, respectively, which suggests a very high-quality film prepared by an electrodeposition process. Transport measurements for the ED films show current density values of 3 × 105 A/cm2 at 77 K in zero field. Single-layer thallium-oxide films with Pb, Bi, and Sr substitution offer the potential for operation at 77 K in practical magnetic fields of 3-5 T.
