摘要：

Novel nanocrystalline glass-coated Fe40Co38Mo4B18 microwires are introduced. They combine the advantages of nanocrystalline alloys exhibiting simultaneously increased Curie temperature and magnetic bistability, which is required for modern sensoric and spintronic devices. Positive magnetostriction of the crystalline FeCo grains results in a magnetic bistability, whereas good soft magnetic properties remain stabilized. As a result of the mechanical stress induced by the glass coating, the optimum temperature range for thermal treatment is enhanced up to 600 degrees C.
