(a) AFM image for a film obtained after a deposition time of 200 s, (b) 300 s, (c) 400 s, and (d) 500 s. An AFM line profile on different samples is shown in (e) and (f) plot of rms roughness vs deposition time and distance between columns vs deposition time. All AFM images are , with scale 20 nm.
PSD function curves calculated for thin films obtained with different deposition time.
Room temperature hysteresis loops for films obtained after a deposition time of 200 s, (b) 300 s, and (c) 400 s in parallel field. Inset shows the corresponding hysteresis loops for perpendicular field and (d) MFM image for a film deposited at 300 s (, scale 200 m Deg).
