Microwave and millimeter-wave multiferroic devices
Abstract
The coupling between the electric and magnetic subsystems in a magnetoelectric (ME) material opens up the possibility of novel sensors and devices. Since the composites show very strong ME interactions, several research groups in recent years focused on the possibility of microwave and millimeter-wave devices based on the converse ME effects, such as dual E- and H-tunable 1–110 GHz devices and miniature antennas. Studies, to date, have been focused on E-tuning of magnetic modes, hybrid spin-electromagnetic resonance, and FMR in composites with spinel ferrites, hexagonal ferrites, or yttrium iron garnet and PZT, PMN-PT, or BTO for ...
