Abstract

We analyzed the temperature, the magnetic field and the normal layer thickness dependences of the pinning force F_p in superconductor (S)-normal metal (N)-superconductor (S) (SNS) multilayers in the framework of the Ginzburg- Landau (GL) theory with the step-like parameters. In particular we studied the temperature dependence of the magnetic field H_peak which corresponds to the pinning force maximum F_pmax in the F_p(H) dependence. It was shown that for temperature well below the critical value the magnetic field of the periodic solution of the GL equation H_D corresponds to the field H_peak and is function of the temperature. Our results are in good agreement with the recent experiments on Nb/Pd multilayers.
