Paper Abstract

We analyzed the temperature, the magnetic field and the normal layer thickness dependences of the pinning force Fp 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 Hpeak which corresponds to the pinning force maximum Fpmax in the Fp(H) dependence. It was shown that for temperature well below the critical value the magnetic field of the periodic solution of the GL equation HD corresponds to the field Hpeak and is function of the temperature. Our results are in good agreement with the recent experiments on Nb/Pd multilayers.
