Growth of Barium Hexaferrite Nanoparticle Coatings by Laser‐Assisted Spray Pyrolysis - Progress in Nanotechnology - Wiley Online Library

Barium Hexaferrite (BaM) nanoparticle coatings have been deposited by a laser assisted spray pyrolysis method. The concentration of the Ba and Fe inorganic salts in the starting aqueous solution determined the final particle size. Films with particle size tunability in the range of 30-100 nm have been grown. Incorporation of CO₂ laser heating in the process enabled the growth of well-defined smaller particles in comparison to thermal pyrolysis. Structural and morphological characterization of the films has been carried out by x-ray diffraction, Scanning Electron Microscopy (SEM), and Atomic Force Microscopy (AFM). This chapter presents the results of a systematic study that was carried out to determine the optimum growth parameters to form nanoparticle BaM coatings with particle size control.
