A brief review of ferroelectric control of magnetoresistance in organic spin valves

Ferroelectricity has been introduced to organic spin valves to manipulate the magneto transport, providing a knob to vary the interfacial energy alignment and the interfacial crystal structures, both are critical for the spin transport at the interface. In this review, we discuss the recent efforts of controlling magnetoresistance of organic spin valves using ferroelectricity, where the ferroelectric materials are either inserted as an interfacial layer or used as the spacer material. These efforts advance the understanding of the spin transport through the ferromagnet/organic interfaces and the results promise more functionality of organic spintronic devices.149
