Spintronic Transport Device Using a Magnetic Skyrmion Lattice

Magnetic skyrmions are a topologically protected state in certain magnetic systems. Their topological properties make skyrmion states stable and thus a possible basis for memory or energy storage spintronic devices. We present preliminary results for a transport device that uses a skyrmion lattice in the magnetic insulator Cu$_{2}$OSeO$_{3}$ as a precursor to an energy storage system. Data from the transport device are shown and these are used to test the underlying elasticity theory for the skyrmion lattice.
