(a) AFM surface relief scan of an annealed ultrathin ferrite garnet film of nominal composition Bi₂Dy₁Fe₄Ga₁O₁₂ and 1.7 nm thickness, deposited onto a GGG substrate. (b) Partial surface scan data from a flatter part of scan shown in (a). The larger nanocrystallites’ height reaches 5 nm. (c) Surface relief profile measured along a scanned line in a garnet film of nominal composition Bi₂Dy₁Fe₄Ga₁O₁₂ and 1.7 nm thickness and (d) starting 400 nm-long part of the line scan profile shown in (c).
