We study the effect of the interfacial transparency on the Josephson currentin a diffusive ferromagnetic contact between two superconductors. In contrastto the cases of the fully transparent and the low-transparency interfaces, thecurrent-phase relation is shown to be nonsinusoidal for a finite transparency.It is demonstrated that even for the nearly fully transparent interfaces thesmall corrections due to weak interfacial disorders contribute a smallsecond-harmonic component in the current-phase relation. For a certainthicknesses of the ferromagnetic contact and the exchange field this can leadto a tiny minimum supercurrent at the crossover between 0 and $\pi$ states ofthe junction. Our theory has a satisfactory agreement with the recentexperiments in which a finite supercurrent was observed at the transitiontemperature. We further explain the possibility for observation of a largeresidual supercurrent if the interfaces have an intermediate transparency.Comment: 7 pages, 4 figure
