Energy harvesting derived from magnetization reversal in FeCoV wire
2012 IEEE Sensors, 2012 A fast magnetization reversal accompanied by a large Barkhausen jump in a magnetic wire is utilized in speed sensors, rotation sensors, and other applications. This magnetization reversal induces a pulse voltage in a pick-up coil. The sensor structure consists of the magnetic wire attached directly to a movable object, the pick-up coil, and a single ...

Effective excitation by single magnet in rotation sensor and domain wall displacement of FeCoV wire [PDF]
Journal of Applied Physics, 2011 Recently, a sensor structure consisting of magnetic wires attached directly to a rotating shaft, a pick-up coil, and a pair of magnets separately located outside the rotor was proposed. This paper presents a structure whose excitation source is just a single magnet. This structure decreases the cost of the previous sensor while retaining its advantages.

Control of Demagnetizing Field and Magnetostatic Coupling in FeCoV Wires for Zero-speed Sensor
INTERMAG 2006 - IEEE International Magnetics Conference, 2006 In this paper, a measurement of the effect of the demagnetizing field and a method of reducing these disadvantages by etching both ends of the wire are studied. A magnetization reversal in magnetic wires with bistable magnetization states induces pulse voltage in a pickup coil.

Control of demagnetizing field and magnetostatic coupling in FeCoV wires for zero-speed sensor [PDF]
Control of demagnetizing field and magnetostatic coupling in FeCoV wires for zero-speed sensorA fast magnetization reversal in twisted Vicalloy wires is utilized in speed sensor, rotation sensor, and other applications. It has the advantage of generating a constant pulse voltage in a pickup coil which is independent of a changing rate of the applied magnetic field.
