Influence of the defects on magnetic properties of glass-coated microwires

摘要

Using magnetic characterization, electronic and optical microscopy we studied magnetic properties and different kind of defects in glass-coated microwires containing Co. We observed that Co addition allows improvement of magnetic softness. We also observed the oxygen presence in "defective" regions on the metallic nucleus surface and indications of chemical interaction between the glass-coating and the metallic nucleus.
