摘要： PURPOSE: To obtain large Barkhausen effect with which stable and high output magnetic characteristics can be obtained by a method wherein a ratio of the radius of curvature of circular arc, which is in a free state where external force is removed, to wire diameter is specifically prescribed. CONSTITUTION: A Vicalloy alloy wire of 50Co-40Fe-10V (wt.%) is wire-drawn using dies, it is annealed in a hydrogen atmosphere, and wire is obtained. A tensile bending work is conducted at a specific speed while tensile load is being given to the wire and the wire is being pressed to the mold, the effective part of working is taken out, and a magnetosensitive wire is obtained. The ratio R/d of the radius of curvature (R) to the wire diameter (d) of the wire is set in the range of 65 to 95. As a result, the magnetism-sensitive wire, having large pulse output and stabilized and uniform characteristics, can be manufactured at low cost.

摘要： PURPOSE: To provide a label for article monitoring which generates a large output signal even when the label is mush smaller in wire diameter and length than a label which uses an amorphous metal wire. CONSTITUTION: An Fe-Si alloy thin wire 13 is sandwiched between a 1st base material 11 and a 2nd base material 12 which are formed into a tape shape. This allows that thin wire 13 is formed out of an alloy of 6.2-6.7wt.% in Si density, and the wire diameter is 30-90μm and the length is 300-500 times as large as the wire diameter, so that abrupt magnetism inversion is caused when an alternating magnetic field exceeding its coercive force is applied. The base materials 11 and 12 are cut to have a proper length together with the alloy thin wire 13 and used. A display part 16 such as a bar code that can optically be read is printed on the top surface of the 1st base material 11 or 2nd base material 12, and an adhesive layer and peeling paper are provided on the rear surface side. This label 10 is peeled off the peeling paper and stuck on an article.
