Abstract

We report on the results of measurements of the angular dependence of magnetization of high-T c superconducting YBa2Cu3O7−δ, and La1.85Sr0.15CuO4 thin films and superconducting/ferromagnetic YBa2Cu3O7−δ/Nd0.67Sr0.33MnO3 superlattices. We compare our present results to our results, previously obtained for YBa2Cu3O7−δ and Bi2Sr2CaCu2O8 single crystals. We discuss the influence of the presence of Nd0.67Sr0.33MnO3 sublayers in YBa2Cu3O7−δ/Nd0.67Sr0.33MnO3 superlattices on the critical temperature, flux pinning, and the critical field for the first vortex penetration.
