Abstract:

Thin uniform films with good adhesion of the type MIIFe2O4 (M = Cu, Mg, Zn) with grains from 30-100 nm (M = Cu, Mg) to 0.15-2 I¼m (M = Zn) are prepared by spray-pyrolysis using ethylene glycol solutions of mixed-metal citric complexes. The thin ferrite films are investigated by atomic force microscopy and multifractal analysis.
The generalized dimension Dq and the singularity spectrum f(±) provided quantitative values that describe the degree of heterogeneity in the 3D surface geometry at nanometer scale. Detailed surface characterization of the surface topography was obtained using statistical parameters, according with ISO 25178-2: 2012. These results demonstrate that multifractal analysis could be a useful tool for characterizing quantitatively the 3D surface geometry of thin ferrite films deposited by spray-pyrolysis.
