Abstract Scope |
Creating denser computational devices based on electronic transistor devices is limited in part by their efficiency and heat dissipation. Among the alternatives being pursued are devices employing magnetic spins to store and transmit information, which could be more efficient due to far fewer electrons being transported. Our research examines a class of magnetic structures known as skyrmions, “bubbles” of in-plane magnetic domain, which possess desirable properties as an information medium due to their small size, relative stability, and speed of transport. Using micromagnetic simulation, we show that the dzyaloshinskii-moriya interaction (DMI) in a hypothetical material is able to bias how a perpendicular magnetic field applied to a skyrmion will switch its chirality to prefer one direction or another, which could be a means to reliably encode information in a magnetic memory device. |
