Transport in a Spintronic Device Using a Magnetic Skyrmion Lattice

Magnetic skyrmions are a topologically protected state in certain magnetic systems. Their topological properties make skyrmions stable and thus a possible basis for memory or energy storage spintronic devices. We present results for a transport device that uses a skyrmion lattice in the magnetic insulator Cu₂OSeO₃ as a precursor to an energy storage device. Data from the transport device and its fabrication are presented. The transport data are then used to test the underlying elasticity theory for the skyrmion lattice.
