RBS studies on YBa {sub 2} Cu {sub 3} O {sub 7-{delta}} thin films deposited by sputtering

摘要: Interdiffusion of constituent elements of YBCO films have been studied by RBS. In this technique the incident ion is directly scattered by the target elements individually without secondary matrix effects. The composition of the multi element film, however, affects the stopping power of the material through which the ion traverses. The films were superconducting with a transition temperature of T{sub c}(R=0) of 90K and critical current density J{sub c}(at 77K) {approx_equal}10{sup 6}Acm{sup -2}. 2 figs.
