SBIR-STTR Award

In this proposal, Boston Applied Technologies, Incorporated (BATi) together with University of Minnesota proposes to develop a high quality epitaxially grown multiferroic thin film heterostructure through a simple wet chemical route, which has been demonstrated the capability of growing high quality multilayer films through nano-engineering and introducing proper buffer layers. The feasibility of developing of an electrically tunable RF isolator utilizing of the magnetoelectric coupling effect of the heterostructure will be evaluated.

Microwave technologies have found a broad range of and growing applications, especially in the area of communications. Many microwave tunable devices are bulky and incompatible with RF semiconductor IC technology. The slow tuning response speeds, high material losses, and device noise at higher frequencies have also limited their widespread applications.Recent advances in processing complex oxide and multiferroic thin films present the opportunity for state-of-the-art microwave components. These technologies open the way for establishing electrically tuned ferromagnetic RF resonance devices with reduced bias fields, faster tuning speed, and minimized device size.
