Popis: A novel monolithic lateral SNS structure of Bi-oxide systems has been developed in which the compositions of films were locally controlled in the lateral direction. Lateral SNS (BiSrCaCuO/BiSrCuO/BiSrCaCuO) structures which were made from a Ca-F/BSCO layer on MgO substrates have been developed. The BiSrCaCuO area, with a thickness of 150 nm, is composed of a 2212 phase with high crystallinity of the c-axis preferred orientation, and shows zero resistance at 85 K. The BiSrCuO indicates sufficiently low resistivity to be used as a normal barrier for SNS Josephson junctions. BSCO formation using Ca-diffusion into the surfaces of 2201 single crystals was successfully carried out.
