Abstract : ONR Grant N00014-06-1-0889 has supported a program on new magnetic materials in thin film and bulk form for Navy microwave devices and systems in particular and overall defense applications in general. During the funding period from June 4, 2006 to August 3, 2007, there were numerous accomplishments. Seven archival papers were published on (1) ferromagnetic resonance (FMR) measurements in Permalloy films with an emphasis on the comparison of measurement methods, (2) FMR resonance saturation and Suhl instability processes in Permalloy films, (3) low field effective linewidth in polycrystalline ferrites, (4) Fermi-Pasta-Ulam recurrence for spin wave solitons in yttrium iron garnet (YIG) film Strips in a feedback ring system, (5) the Hamiltonian formulation of two magnon scattering microwave relaxation, (6) fundamental properties and structure connections for Fe-Ti-N films, and (7) the detection and analysis of the nonlinear ferromagnetic resonance response in Permalloy films by the magneto-optic Kerr effect.
