Abstract
Here we examine the ferromagnetic/superconducting proximity effect in half-metallic ferromagnetic La0.7Ca0.3MnO3 and high-Tc superconducting YBa2Cu3O7 artificial structures. We have found experimental evidence for the coupling between superconducting layers through ferromagnetic spacers in superlattices. This is consistent with a long-range proximity effect in half-metal ferromagnet/d-wave superconductor structures.
