    • 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.
    • 用多位数字信息编码玻璃涂层的非晶态金属微丝。 编码是通过磁学,光学或通过磁和光编码过程的组合实现的。 通过选择性地避免玻璃涂层和非晶金属合金芯之间的界面应力来改变构成磁畴结构来进行磁编码。 也可以通过非晶金属芯的选择性表面结晶来实现,以产生受控的磁偏置场。 光学编码与玻璃涂层有关。 通过荧光元件沉积,荧光元件涂层的图案化去除,布拉格光栅和热激活图案沉积容易实现。 用于玻璃涂覆的非晶金属微丝的磁和光多位编码方法可以单独使用或以多余或互补的方式共同使用。 本发明的编码微线可以组装成用于电子物品监视的标签以及许多其它结构。
