I will summarize some of our recent work in the field of cuprate superconductors, with focus on two issues: i) hybrid systems that combine the superconductors (S) with ferroic (F) materials (ferromagnet, ferroelectrics) [1,2] and ii) artificially nanostructured films.
I will argue that both approaches offer many opportunities for amusing physics, and also for novel functionalities (maybe). This, on the one hand, because competing interactions at S/F interfaces yield physical properties which are often inexistent in nature. On the other hand, because the possibility to structure oxide materials at the truly nanoscale  [3] allows tailoring the macroscopic properties of these systems.
