Abstract

Epitaxial thin films of Barium Ferrite (BaFeO3) have been fabricated by the pulsed laser deposition technique on a Si substrate. The magnetic parameters were measured using vibrating sample magnetometer. The ferromagnetic resonance (FMR) measurements of the thin film were found to be close to the parameters associated with bulk materials. The Atomic Force Microscope was used to determine the surface morphology at different temperatures. The derivative FMR line width was measured to be 70 Oe at 60 GHz and 50 Oe at 90 GHz. The relationship among the Coercivity, crystalline orientation, and grain shape and size is presented.
