N2 - This work is devoted to the investigation of the effect of an external magnetic field (MF) applied to a sonochemical synthesis. The paper presents results on the preparation of both aggregated magnetite nanoparticles and the destabilization of a magnetite hydrosol that is formed without a MF. The results reveal a difference in morphology, size, and magnetic properties of the product obtained under a MF. They also show that the applied magnetic field affects the stabilization mechanism of the magnetite particles in an aqueous solution and destroys the stable hydrosol formed without a MF. Instead, the formation of tree-like, aggregated structures composed of small particles is observed.
