Proximity effect in zero field with the Landau-Ginzburg equation. II

Based on the results of the preceding paper, we find that for a film sandwich composed of a superconductor with higher transition temperature {ital T}{sub {ital S}} and a superconductor with lower transition temperature {ital T}{sub {ital N}} ({ital S}-{ital S} lamina), the transition temperature is determined by the following equation: {ital B}{sub 0}{ital d}{sub {ital N}}{xi}{sub {ital S}}/{ital d}{sub {ital S}}(1{minus}{ital T}{sub {ital c}{ital S}{ital S}}/{ital T}{sub {ital S}}){minus}{ital d}{sub {ital S}}={ital B}{sub 1}{ital d}{sub {ital N}}/{radical}{ital T}{sub {ital c}{ital S}{ital S}}/{ital T}{sub {ital N}}{minus}1 , which can be converted into an equation of third order in {ital T}{sub {ital c}{ital S}{ital S}}. Numerical calculations indicate that this model fits experimental results very well, and a new general treatment of the proximity effect can be developed.
