Description
We computationally study the frustrated magnetic configurations of a thin soft magnetic layer with the boundary condition fixed by underlying hard magnets. Driven by geometrical constraints and external magnetic field, transitions between frustrated energy minima result in magnetic hysteretic behavior. The presence of soft-magnet introduces strong undulations in the energy landscape in a length scale set by the magnetic property of the soft magnet. We propose a possible use of the phenomena to locally control the movement of magnetic nanoparticles.
