Structure, Magnetic and Microwave Properties of Granular Fe_{_x}(SiO₂)_1-x Alloys Obtained by Mechanochemical Synthesis

Abstract:

The structural-phase composition, magnetic and microwave properties of Fe_x(SiO₂)_1-x (x=30, 70, 90, 95) nanocomposites have been studied. The composites are produced by high-energy ball milling with either Ar or acetone as a milling medium and milling time of 1 to 64 h. The microwave magnetic properties of the composite in the frequency range of 0.1 to 6 GHz are shown to depend slightly on the phase composition and be governed mainly by the particle size. Reduction of the particle size to about 1 μm results in elimination of magnetic loss at frequencies below 1 GHz, which is attributed to the domain walls motion.
