Layered magnetostrictive-ferroelectric structures are multifunctional due to their response to mechanical and electromagnetic forces. Investigations on microwave magneto-electric MEinteractions were performed on ferrite-ferroelectrics layered structures. Systems studied include yttrium iron garnet YIG-lead zirconate titanate PZT or YIG-barium strontium titanate BST. Our efforts have resulted in the following breakthroughs in experimental and theoretical understanding i The observation of strong microwave ME interactions in YIG-PZT ii Theory and experiments on the creation and propagation characteristics of hybrid spin-electromagnetic waves in YIG-BST and iii Fabrication of electric field tunable YIG-PZT and YIG-BST resonators and phase shifters operating at 3-12 GHz. These results have been published in 35 journal articles.
