DC and microwave properties of YBCO microbridges formed across a shallow step in MgO substrates were studied. Shallow steps, 2-5 nm high, were Ar ion beam etched with an angle of incidence of 60 Β° in an MgO substrate. A 200 nm thick YBCO film was grown by pulsed laser deposition. The linewidth of th
