摘要： The present invention provides a compound powder for making magnetic powder cores, a kind of magnetic powder core, and a process for making them. Said compound powder is a mixture composing of powder A and powder B, the content of powder A is 50-96 wt % and the content of powder B is 4-50 wt %, wherein powder A is at least one selected from iron powder, Fe—Si powder, Fe—Si—Al powder, Fe-based nanocrystalline powder, Fe-based amorphous powder, Fe—Ni powder and Fe—Ni—Mo powder; powder B bears different requirement characteristics from powder A and is at least one selected from iron powder, Fe—Si powder, Fe—Si—Al powder, Fe-based nanocrystalline powder, Fe-based amorphous powder, Fe—Ni powder and Fe—Ni—Mo powder. Said powder B adopts Fe-based amorphous soft magnetic powder with good insulation property as insulating agent and thus core loss of magnetic powder core decreases. The decrease of magnetic permeability of magnetic powder core resulting from a traditional insulating agent is remedied and the initial magnetic permeability of magnetic powder core is improved by taking advantage of soft magnetic properties of Fe-based amorphous powder.

摘要： A glass-coated amorphous metallic microwire is encoded with multi-bit digital information. Encoding is achieved magnetically, optically or through a combination of magnetic and optical encoding processes. Magnetic encoding is carried out by modifying the constituent magnetic domain structure through selective relief of interfacial stress between the glass coating and the amorphous metallic alloy core. It is also achieved by selective surface crystallization of the amorphous metallic core in order to produce a controlled magnetic bias field. Optical encoding is associated with the glass coating. It is readily achieved by fluorescent element deposition, patterned removal of fluorescent element coating, Bragg grating, and thermally activated pattern deposition. The magnetic and optical multi-bit encoding approaches for glass-coated amorphous metallic microwire can be used individually or collectively in either a redundant or a complementary manner. Encoded microwire of the instant invention can be assembled into tags for electronic article surveillance and into numerous other structures as well.
