Abstract
A planar tunnel diode with Ba/sub 1-x/K/sub x/BiO/sub 3/ (BKBO) and Ag electrodes were fabricated. The dynamic conductance of the junction was similar to that found with conventional BCS superconductors. Using weak coupling theory, the undepaired transition temperature, spin-orbit scattering rate, and diffusion constant of BKBO were determined. The Pauli-limited critical field was calculated and compared to the measured resistive transitions of the BKBO film in magnetic fields. The Pauli-limited field is observed to occur generally at the field where the normal-state resistance is restored.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
