Many applications of Josephson junctions require that the sidelobes of the critical-current patterns as a function of magnetic field be as small as possible. The sidelobes can be significantly suppressed by appropriate choice of junction geometry. This paper emphasizes that suppression is not just a
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 ยฐ in an MgO substrate. A 200 nm thick YBCO film was grown by pulsed laser deposition. The linewidth of th
