Magnetic response of ferromagnet–superconductor bilayers

Magnetic measurements on a ferromagnet/insulator/superconductor (La2/3Ca1/3MnO3/SrTiO3/YBa2Cu3O7−x) structures were performed with the field applied parallel to the plane of the film. We observed an evidence of a modification of the ferromagnetic domain structure in the magnetic layer induced by the...

Description
Summary:Magnetic measurements on a ferromagnet/insulator/superconductor (La2/3Ca1/3MnO3/SrTiO3/YBa2Cu3O7−x) structures were performed with the field applied parallel to the plane of the film. We observed an evidence of a modification of the ferromagnetic domain structure in the magnetic layer induced by the superconducting transition in the neighboring superconducting YBa2Cu3O7−x layer. ► Magnetic measurements of superconductor–insulator–ferromagnetic structure. ► Insulator eliminates electronic interaction between ferromagnet and superconductor. ► Superconducting transition modifies ferromagnetic domain structure.
