摘要： A magnetic implement has a gap size ranging from about 1 to about 20 mm. The implement comprises a magnetic core composed of an amorphous Fe-based alloy. A physical gap is disposed in the core's magnetic path. The alloy has an amorphous structure; is based on the components: (Fe—Ni—Co)—(B—Si—C). The sum of its Fe+Ni+Co content is in the range of 65–85 atom percent. Advantageously, the core exhibits an overall magnetic permeability ranging from about 40 to about 200 and enhanced magnetic performance.

摘要： A metallic glass alloy ribbon consists essentially of about 70 to 87 atom percent iron. Up to about 20 atom percent of the iron is replaced by cobalt and up to about 3 atom percent of the iron is replaced by nickel, manganese, vanadium, titanium or molybdenum. About 13-30 atom percent of the element balance comprises a member selected from the group consisting of boron, silicon and carbon. The alloy is heat-treated at a sufficient temperature to achieve stress relief. A magnetic field applied during the heat-treatment causes the magnetization to point away from the ribbon's predetermined easy magnetization direction. The metallic glass exhibits linear DC BH loops with low ac losses. As such they are especially well suited for use in current/voltage transformers.

摘要： Electronic article surveillance markers, methods for their production and for their use are disclosed. In one aspect there is provided an integrated deactivatable hybrid marker which can be used both in radio frequency and magnetic harmonic article surveillance systems. The harmonics generating element or elements of the marker are inserted into a RF resonant circuit as an active part of the circuit. The deactivation of the marker is accomplished by employing another element of high coercivity magnetic material. When placed in a RF interrogation field, the hybrid marker causes an increase in absorption of transmitted signal in order to reduce the signal in the receiving coil of the RF surveillance system. When placed in an interrogation zone of a magnetic harmonic article surveillance system, the marker generates high harmonics of the interrogating frequency that can be detected by the receiver of the surveillance system. In addition both the RF and harmonic functions of the hybrid marker can be deactivated by a single process. Further more, the use of conductive paste material to print the RF circuits is disclosed to achieve a low cost manufacturing process.
