Abstract
The conductivity and magnetoresistance of a practically useful ferrite compound are found to be electrically programmable in a nonvolatile manner. Electric-double-layer gating using an ionic liquid changes the surface oxidation state of spinel zinc ferrite via reversible redox processes. This unique electric-field effect, distinct from conventional electrostatic carrier doping, provides a new route for developing oxide-based field-effect devices.
