Description |
CoFe2O4/ZnFe2O4 bilayers were deposited by the pulsed laser deposition on amorphous fused quartz substrate at substrate temperature of 350 degrees C and in oxygen pressure of 0.16 mbar. The films were studied after ex-situ annealing for 2 h in air at various temperatures up to 650 degrees C. The magnetic properties of the bilayers were studied at 300 K and at 10 K. Ferromagnetic resonance was carried out at x-band frequencies at room temperature. It was found that as a result of annealing, the diffusion between Co ferrite and Zn ferrite starts around 350 degrees C and leads to a large line width system having magnetization, which remains undetected by Ferromagnetic resonance.
