摘要： A magnetic sensor device comprising a magnetic element and a wire wound around the magnetic element. The magnetic element has a cross-sectional area of not more than 0.55 mm.sup.2 and a saturation magnetostriction constant .lambda.s whose absolute value is smaller than 1.times.10.sup.-6, with Sw/Sm being equal to or smaller than 9, provided that Sw is the cross-sectional area of the wire and Sm is the cross-sectional area of the magnetic element. Preferably, the magnetic element has an elastic limit .sigma.m greater than 1,000 MPa, and the elongation the magnetic element experiences upon application of a stress equal to the elastic limit .sigma.m is between 1.0% and 5.0%. It is also preferable that the magnetic element and the wire are covered with a resin layer to form an integral unit.

摘要： A compact and superior magnetic marker for an electronics apparatus for surveillance of article comprises at one or more wire members and a plane member contacting substantially directly to each other. An angle of the magnetic easy axis of the plane member relative to the longitudinal direction of the wire member is between 40.degree. and 90.degree. to show large Barkhausen reversal. An influence of demagnetizing field can be reduced by using the simple structure. The magnetic marker can be produced continuously at a low cost.

摘要： A magnetic marker of the present invention includes a magnetic thin wire for generating pulses and bodies of soft magnetic materials that are arranged close to the two ends of the thin wire that have a smaller coercive force than the magnetic thin wire. The magnetic thin wire has a diameter of 60-115 .mu.m and has a ratio of B.sub.r /B.sub.s of a B-H loop of 0.8 or more. Thus, a small magnetic marker can be formed which provides a large Barkhausen effect even if it contains a very short magnetic thin wire.
