Eddy currents in a superconductor shield the magnetic field its interior and are responsible for formation of stray outside superconducting structure. The can be controlled by external affect magnetization dynamics system placed range. In case hybrid consisting strip over layer, we predict theoretically confinement spin waves well static field. number bound states their frequencies an We have presented results semi-analytical calculations complemented numerical modeling.
