Abstract: The numerical simulation method was used to study the distribution of the gradients of the magnetic stray fields over a ferrite-garnet film containing a hexagonal lattice of cylindrical magnetic domains under the application of a control magnetic field. The features of the motion of magnetically marked cells over the surface of such a film were experimentally studied. It was found that the "magnetic ratchet" mechanism is applicable to the motion of magnetic cells over the surface of such a film, and, unlike the same mechanism acting during the motion of magnetic cells over a strip domain structure, it is possible to move a magnetically marked cell near the surface of the ferrite-garnet film in an arbitrary direction specified by a combination of external control fields. Stable motion of magnetically marked cells in an arbitrary direction was experimentally obtained.
