Abstract

DC and AC magnetic properties of Fe-based bulk amorphous alloys as thick meltspun ribbons, cast rods and torroids are investigated. The influence of the preparation conditions, composition, frequency, and treatments on the electrical and magnetic characteristics is discussed. The magnetic behaviour of amorphous wires and microwires is presented. The correlation between the diameter of the wires, the magnitude of the GMI effect and the surface magnetic permeability is discussed. Arrays of amorphous NiP and CoP nanowires with diameters near 200 nm have been obtained using electrodeposition. The microstructure and magnetic properties of the nanowire arrays strongly depend on the composition.
