All-oxide superconductor/ferroic hybrids

This short review focuses on interface interactions in hybrid heterostructures which combine high-temperature superconductors, ferromagnets and ferroelectrics. We specifically examine two different phenomena. One of them is electric-field effects at superconductor/ferroelectric interfaces, which allow a nonvolatile, reconfigurable nanoscale modulation of superconductivity. The second phenomenon is the proximity effect at superconductor/ferromagnet interfaces. We focus in particular on the penetration of superconducting correlations into half-metal ferromagnets. For both phenomena, an overview is given on materials' issues, fabrication techniques, physical mechanisms and related devices.
