摘要：

We report the spatially resolved transport properties of a three-layer YBa2Cu3O7-delta 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 YBa2Cu3O7-delta spiral reveals a reduced zero resistance critical temperature at the steps and edges of the insulator.
