摘要
The invention refers to nanocrystalline magnetic glass-covered wires and to a process for their production. The wires consist of a metallic nanocrystalline core with diameters by the order of 10-6 m having compositions based on transition metals and metalloids and other additional metals, and a glass cover having the thickness of the wall by the same order of magnitude. The nanocrystalline wires present high or medium saturation induction, nearly zero magnetostriction and values of the coercive field and of the magnetic permeability in function of the requested applications. The nanocrystalline glass-covered wires are used in electronics and electrotechnics to achieve inductive coils, mini-transformers, magnetic shields, devices working on the basis of the correlation between the magnetic properties of the metallic core and the optical properties of the glass cover.
