Spintronics advances: Controlling magnetization direction of magnetite at room temperature

Spintronics -- based on the principles of electron charge and magnetic spin -- goes beyond the limits of conventional electronics. However, spintronic devices are yet to see advances, because controlling the magnetization angle in the magnetic material is difficult. Now, scientists have developed an all-solid redox device composed of magnetite thin film and a solid electrolyte containing lithium ions that successfully manipulated the magnetization angle at room temperature, sparking a possible revolution in the field of spintronics.
