Congratulations to Jeremy Levy, Patrick Irvin, and Feng Bi for their patent titled "Oxide Interface Displaying Electronically Controllable Ferromagnetism!"

Magnetism forms the basis for non-volatile storage in hard disk drives. A new field called “spintronics” aims to use electronics and electron spin to process information; however, it has been difficult to find appropriate materials capable of controlling magnetic properties using electronics. Pitt innovators led by Jeremy Levy have identified a new phase of an oxide heterostructure composed of two insulating oxides that exhibits a novel ferromagnetic phase which is completely electrically controllable and stable at room temperature, a concept hailed as the “holy grail” of the field and which would open up an incredible wealth of new opportunities for technological exploitation. This new electronically controlled ferromagnetic phase promises lower power consumption, less heat dissipation, non-volatility, and the possibility of deeper integration of logic and memory for classical and quantum computing applications. Levy is currently leading a multi-institution research team on a $7.5 million grant from the Office of Naval Research to develop new types of quantum computers based on electron spin.
