Antiferromagnetic Magneto-electric Memory and Logic

Peter Dowben (University of Nebraska/Lincoln), Center Director

The AMML Center will focus on developing novel device concepts that will greatly extend the practical limits for energy-efficient computation. The associated antiferromagnetic (AFM) order parameter will be exploited in the proposed devices as a state variable to ensure their nonvolatile operation. As has been demonstrated by the PIs of this project, the AFM order parameter in ME antiferromagnets can be reversibly switched by an external electric field, providing exceptional means for controlling magnetism by exploiting the very large boundary polarization associated with antiferromagnetic magnetoelectrics. This approach to writing the magnetic information allows for a decrease in energy consumption per write operation by two orders of magnitude, as compared to the relevant schemes associated with magnetic tunnel junctions.
