Magnetic materials with strong ferromagnetic precession properties and low damping factors.
The proposed SBIR Phase I program is to establish a ferromagnetic resonance (FMR) measurement setup that is capable of characterizing the FMR spectrum with high sensitivity and over a broad frequency, as well as nonlinear behaviors at high microwave power. The proposed effort also includes modeling effort in order to predict the figure of merit (FOM) for high power microwave generation, which is related with damping constant and the critical rf magnetic field above from which nonlinear behavior emerges. Finally, we will also investigate the guidelines and experimental possibility to fabricate magnetic materials with optimized FOM. These studies will provide much needed measurement tools and guidelines for Phase II magnetic material development and optimization for high power microwave generation.
