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