The properties of Y1Ba2Cu3O7−δ thin films with silver doping prepared by spray pyrolysis
Superconducting, silver‐doped films of Y1Ba2Cu3O7− δ have been deposited by spray
pyrolysis of aqueous nitrate solutions onto MgO substrates. The superconducting transport
properties, microstructure, and microwave losses have been characterized for various
amounts of AgNO3 added to the spraying solution. These films had resistive transition
temperatures between 79 and 85 K with widths from 3 to 7 K. The room‐temperature
resistivity was a strong function of the silver doping, dropping by a factor of 50 for the heavily …
