“…Then, it is possible to smoothly change magnetic permeability, controlling by the restructuring of magnetic alloy from the amorphous into the nano-crystalline state. The next sample of composite material consists of organosilicon thermo-stable matrix and mixed nanocrystal-amorphous magnetic filler with grain size near 50 m (Kuznetsov et al, 2005;Bibikov et al, 2007). Using the microscope of atomic forces, it was shown (Fig.7) that a process of formation of nanocrystalline areas in the amorphous matrix takes place during mechanical and thermo treatment of the alloy.…”
