Large Barkhausen jump in Fe/Co laminated films

AIP Advances
When torsional stress is applied to a Fe–Co–V wire and a magnetic field is applied in the longitudinal direction of the wire, a pulse voltage is generated in the search coil wound around the wire due to a large Barkhausen jump. This pulse voltage has the

Improvement of Pulse Voltage Generated by Wiegand Sensor Through Magnetic-Flux Guidance [PDF]

Sensors, 2020
Magnetization reversal in a Wiegand wire induces a pulse voltage in the pickup coil around the wire, called the Wiegand pulse. The Wiegand sensor features the Wiegand wire and the pickup coil.

Double large Barkhausen jump in soft/soft composite microwires [PDF]

Journal Physics D: Applied Physics, 2010
The magnetic properties of double layer microwires consisting of a soft FeSiBP amorphous core, an intermediate non-magnetic glass spacer and a softer FeNi outer shell have been investigated. As in the case of other magnetostatically coupled two-phase systems, the hysteresis loops are characterized by two well-defined Barkhausen jumps corresponding each

Induction Pulse of Compound Magnetic Wires by the Large Barkhausen Jump

Journal of the Magnetics Society of Japan, 1997
The compound magnetic sensors using twisted vicalloy and permalloy wire were composed and their basic characteristics were investigated. This compound magnetic wire could generate a pulse voltage with high S/N even when flux change was extremely slow. This type of magnetic sensor seems to be applicable for magnetic recording head when they are prepared

Machine-Learning Detection Algorithms for Large Barkhausen Jumps in Cluttered Environment [PDF]

IEEE Magnetics Letters, 2019
Modern magnetic sensor arrays conventionally utilize state of the art low power magnetometers such as parallel and orthogonal fluxgates. Low power fluxgates tend to have large Barkhausen jumps that appear as a dc jump in the fluxgate output. This phenomenon deteriorates the signal fidelity and effectively increases the internal sensor noise.

Barkhausen jumps in large versus small platelets of natural hematite [PDF]

Journal of Geophysical Research: Solid Earth, 1998
To better understand the physical links among hysteresis properties, defect distributions, and grain size, Barkhausen jumps have been studied in individual platelets of natural hematite from Elba, Italy during hysteresis. Both Bitter patterns and hysteresis curves have been investigated in two very different groups of platelets: large, ∼1‐mm‐sized ...
