- Abstract
A new percolation situation has been found in metal-dielectric nanocomposites containing ferromagnetic components. For a certain concentration of metal atoms, the vectors of spontaneous magnetization of individual nanoparticles exhibit a correlated behavior. As a result, a structure containing a very large number of ferromagnetic nanoparticles shows magnetization reversal in a macroscopic nanocomposite volume in a single giant Barkhausen jump.
