“…Reference to pure iron, T c is markedly enhanced taking its maximum value close to x ∼ 14 at.% V [1]. Recent works [2] point out the very high sensitivity of the Barkhausen effect to the metal concentration in metal-dielectric systems. It was demonstrated that the Barkhausen effect can be used as a very effective method to determine the percolation threshold in composite materials containing ferromagnetic particles.…”
