摘要: Results on the magnetic behavior of glass-coated amorphous wires with metallic nucleus diameters in submicron range are reported for first time. The nearly zero magnetostrictive is different from that observed microwires typical dimensions and similar composition. Submicron bistable, whereas show an almost anhysteretic loop. Bistability maintained even a very thin surface layer, which was shown to display helical anisotropy. origin this specific shape anisotropy becomes dominant at lower nucleus. study opens up way new applications wires.
