The interplay between spatially separated ferromagnetic and superconducting thin films
MetadataShow full item record
Ferromagnetic thin films have been grown via physical vapor deposition utilizing the technique of flash evaporation and characterized by measuring magnetization as a function of magnetic field. An Al thin film was evaporated atop the ferromagnetic thin film and allowed to oxidize in order to produce a thin insulating layer. Finally, two superconducting thin films of nearly equal thickness were evaporated via physical vapor deposition onto the A1₂O₃ insulating layer. Both superconducting films, one coupled magnetically, but not electrically, with the ferromagnetic thin film and the other isolated, were studied by measuring resistivity as a function of temperature in various magnetic fields between 0 G and 2 kG. It was found that the effect of the ferromagnetic thin film decreased the superconducting resistive transition width, or equivalently, that the flux flow resistance has been reduced.
