Millimeter-wave magnetoelectric interactions have been studied through electric field effects on magnetic excitations in bilayers of single crystal barium ferrite and lead zirconate titanate (PZT). An electric field E produces a mechanical deformation in PZT, resulting in a shift δf in the frequency for electromagnetic modes in the ferrite. Reflected power versus frequency profiles at 40–55GHz for a series of bias magnetic field and E=0–10kV∕cm along the c axis of the ferrite showed an increase in δf to a maximum of 8MHz. Theoretical estimates of δf are in agreement with the data.
