Abstract. We examine the interplay between ferromagnetism and superconductivity in La0.3Ca0.7MnO3/YBa2Cu3O7 superlattices showing “coexistence” of magnetism and superconductivity. A depression of the critical temperature is observed when manganite layer thickness is increased between 0.9 and 8 nm, pointing to an interplay between ferromagnetism and superconductivity over nanometer length scales. The possibility of a ferromagnetic/superconducting proximity effect to explain these results is analyzed.
