Influence of the agglomeration in the initial suspension (ferrofluid) on the oriented magnetic structure

Abstract

The process was studied of preparation of oriented BaFe12O 19 films via deposition of BaFe12O19 nanoparticles from a suspension in a magnetic field. The films' structural, microstructural and magnetic properties were investigated by X-ray diffraction, scanning electron microscopy and magnetic measurements. The influence was explored of the particles's agglomeration in the ferrofluid on the films' properties and microstructure. Using time delay deposition, we obtained thick films with a high degree of orientation and good density.
