The behavior of the order parameter close to the superconductor-normal metal interface is researched. The thickness d of the normal layer is arbitrary and the temperature is close to critical. The method of quasiorthogonality to asymptotics is used to obtain boundary conditions. The expression that describes the dependence of the current states on the normal layer's thickness is obtained. Asymptotic forms of solution at large and at small d (relatively to the coherence length) are considered.

В роботі було досліджено рівноважні струмові стани у надпровідних контактах типу SNINS (S – надпровідник, N – нормальний метал, I – діелектрик) за наявності немагнітних домішок довільної концентрації у надпровідних областях. Дослідження проводились для температур, близьких до критичної з використанням теорії Гінзбурга-Ландау. Одержані результати є чинними для широкого інтервалу значень коефіцієнта проходження електронів та довільної товщини нормального прошарку. При дослідженні струмових станів було враховано вплив на струм-фазову залежність ефектів розпаровування.

The behavior of the order parameter close to the NS interface in an SNINS junction is considered. To this end, a linear integral equation, which is valid near the superconductor-normal metal interface, is obtained and researched. The Ginzburg-Landau equation is solved taking into account the effect of the current on the space behaviour of the order parameter. Applying the method of quasiorthogonality to asymptotics, the boundary condition for the Ginzburg-Landau equation is obtained. The calculation of the current states, which can exist in an SNINS junction is carried out. We assume the normal layer thickness to be arbitrary and the temperature to be close to critical.
