Resumo

A method for synthesizing a magnetic fluid with ferromagnetic nanowires based on silicone oil is described, and a magnetorheological effect is demonstrated. The physical characteristics of the resulting ferrophase were studied using optical and scanning electron microscopy, energy-dispersive X-ray spectroscopy, and X-ray phase analysis. The size of the nanowires was measured by dynamic light scattering, for which the conditions for stabilizing ferromagnetic wires in an aqueous solution by coating with polyvinylpyrrolidone were selected.
