Abstract :
NiFe2O4 nanocomposites were characterized by a coplanar waveguide ferromagnetic resonance (FMR) measurement setup. Ferromagnetic resonance fields were analyzed to determine the internal magnetic field in the samples. The effects of sample orientation and particle packing fraction on the FMR behavior are investigated. The results are found to agree with theoretical predictions on high frequency properties of magnetic nanocomposites.
