Barium hexaferrite (BaFe12O19 or BaM) films were grown on c-plane sapphire(0001) substrates by pulsed laser deposition (PLD) to evaluate the effects ofthe laser fluence on their composition, structure, and magnetic properties.Continuum's Surelite pulsed 266nm Nd:YAG laser was employed, and the laserfluence varied systemically between 1 and 5.7 [J/cm2]. Deviations from thestoichiometric transfer between the BaM targets and deposited thin filmsoccurred as the laser fluence changed. The Fe to Ba ratio in the filmsincreased with the laser fluence. The films deposited at the laser fluencesbelow 4 J/cm2 showed undesirable 3-dimensional islands on the surface.Moreover, insufficient laser energy resulted in the deposition of somesecondary phases, for example, barium monoferrite (BaFe2O4) and Magnetite(Fe3O4). On the other hand, laser fluences above 5 J/cm2 promoted resputteringand degraded the film quality, structure, and magnetic properties. BaM filmsdeposited at 4.8 J/cm2 - the optimal laser fluence - showed excellent c-axisorientation perpendicular to the film plane with the anisotropy field of 16 kOeand saturation magnetization of 4.39 kOe. These results clearly demonstrate astrong influence of the laser parameters on the PLD-grown hexaferrite films andpave the path for the high-yield production using PLD systems.
