Abstract :

This presentation will focus on electric field induced nonlinear magneto-electric (ME) interactions in single crystal M-type hexagonal ferrites. The ME interactions result in variations in magnetic order parameters and manifest as tuning of magnetic resonance and the tuning is found to be linear with input electric power. The phenomenon is of importance for a new family of tunable miniature ferrite signal processing for use over 40-110 GHz.
