ELECTRIC FIELD CONTROL OF MAGNETISM IN FERRITES FOR SUB-THZ ELECTRONICS
Abstract
Ferrites are ideal for use in high frequency signal processing devices due to low losses. A key disadvantage in their use, however, is the need for a variable bias magnetic field for operation and tuning the frequency and SWaP (size, weight, and power) considerations. The proposed research on electric field control of magnetic properties is aimed at miniaturization of self-biased ferrite devices for possible integration with semiconductor devices. The motivation is our recent discovery of such effects in strontium hexaferrite. Utilizing microwave measurement technique it was found that non-linear magneto-electric (NLME) interactions in an electric field resulted in significant variation in magnetic parameters that will provide a path for voltage-tuning of ferrite devices.
