Abstract

We report the spatially resolved transport properties of a three-layer YBa₂Cu₃O_7-δ flux transformer using low-temperature scanning electron microscopy. The seven-turn spiral coil is fabricated using a crossover technology with SrTiO₃ as an insulator. The different layers were patterned with shadow masks or optical lithography. We show that the insulating SrTiO₃ film has no shorts and that the overlaying YBa₂Cu₃O_7-δ spiral reveals a reduced zero resistance critical temperature at the steps and edges of the insulator.
