Abstract

Thin ferromagnetic La_2/3Ca_1/3MnO₃ layers are deposited in between two layers of the high-T_c superconductor YBa₂Cu₃O_7-δ (YBCO) by pulsed laser deposition. Using a tailored buffer layer allows the change of the orientation of the CuO₂ planes inside the superconducting layers. With this technique it is possible to produce ferromagnetic barrier layers with high ferromagnetic transition temperatures that are thinner than the coherence length of the adjacent superconductors. Magnetization and electric transport measurements suggest that this geometry might be successful for the generation of ferromagnetic Josephson junctions in high temperature superconducting YBCO.
