Phys.org  October 30, 2023 Magneto-ionics is a unique approach to control magnetism with electric field for low-power memory and spintronic applications. So far, magneto-ionics has been achieved through direct electrical connections to the actuated material. Researchers in Spain have shown that such control can be achieved wirelessly. Without direct wire contact inducing polarization in the conducting material immersed in the electrolyte, promoted wireless bipolar electrochemistry, an alternative pathway to achieve voltage-driven control of magnetism based on the same electrochemical processes involved in direct-contact magneto-ionics. They achieved significant tunability of magnetization for cobalt nitride thin films, including transitions between paramagnetic and […]
