Abstract
ABSTRACTCobalt ferrite (CoFe2O4) thin films were deposited on quartz and single crystalline MgO(001) substrates using pulsed laser deposition (PLD) technique. The orientation of the as-deposited films were investigated as a function of substrate temperature (TS) in the range 200°C – 750°C. Films grown on MgO at higher substrate temperature were found to be (001) oriented while the films grown at lower substrate temperature were polycrystalline in nature. Magnetic measurements reveal that films deposited at lower substrate temperature had lower magnetic moment compared to that of films grown with higher substrate temperature, indicating the correlation between magnetic order and crystallinity. This is attributed to the presence of ordered magnetic domains in the oriented films even though the microstructure remains the same.
