Abstract: The invention refers to amorphous and nanocrystalline magnetic glass-covered wires. The wires consist of a metallic amorphous or nanocrystalline core with diameters by the order of 10−6 m, having compositions based on transition metal-metalloids and other additional metals and a glass cover, having a thickness of the wall by the same order of magnitude. The wires present high or medium saturation inducation, positive, negative or nearly zero magnetostriction and values of the coercive field and of the magnetic permeability in function of the requested applications in a field of electronics and electrotechnics to achieve sensors, transducers, inductive coils, trnasformers, 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.

Abstract: The invention refers to amorphous and nanocrystalline magnetic glass-covered wires and to a process for their production. The wires consist of a metallic amorphous or nanocrystalline core with diameters by the order of 10−6 m having compositions based on transition metal-metalloids and other additional metals and a glass cover having a thickness of the wall by the same order of magnitude. The wires present high or medium saturation induction, positive, negative or nearly zero magnetostriction and values of the coercive field and of the magnetic permeability in function of the requested applications.
