Researchers from the Tokyo University of Science have developed an all-solid redox device composed of magnetite (Fe3O4) thin film and a solid electrolyte containing lithium ions that successfully manipulated the magnetization angle at room temperature.
The researchers say they have developed a surprisingly simple yet efficient strategy to manipulate the magnetization angle in magnetite, a typical ferromagnetic material. This magnetization rotation is caused by the change of spin-orbit coupling due to electron injection into a ferromagnet. The new approach leverages a reversible electrochemical reaction.
The researcher further say that this novel device represents a big step in the control of magnetization for the development of spintronic devices. Moreover, the structure of the device is relatively simple and easy to fabricate.
