Large Barkhausen jump in composite wires
IEEE Transactions on Magnetics, 1991Composite wires consisting of a soft magnetic NiFe-based core and a hard magnetic shell of CrCoFe alloy were investigated. Due to a stress-induced uniaxial anisotropy, the positive magnetostrictive core is remagnetized by a large Barkhausen jump. Two modes of operation are discussed.

Large Barkhausen jumps in relaxed Co-rich amorphous alloy ribbons
IEEE Transactions on Magnetics, 1997The effect of a previous thermal treatment (370/spl deg/C, 30 minutes) on the occurrence of a large Barkhausen jump (LBJ) present in the magnetization process of two Co-rich amorphous ribbons treated by means of current annealing has been studied. The LBJ is characterized by an applied magnetic field called the critical field, H*. The stress dependence

Phase separation as a possible interpretation of large Barkhausen jumps in amorphous ferromagnets
Solid State Communications, 1988Abstract Static hysteresis loops at low magnetic field and temperature dependence of saturation magnetization for the amorphous Co 72.8 Fe 5.2 Si 11 B 11 alloy were investigated and compared with that ones for the amorphous Co 72 Fe 6 Si 11 B 11 alloy.

Investigation and Modeling of Large Barkhausen Jumps Dynamics in Low-Power Fluxgate Magnetometers
IEEE Sensors Journal, 2019Large Barkhausen jumps occur in low-power fluxgates output and seriously affect the signal fidelity and therefore the magnetometer functionality. In this paper, we investigate the occurrence of DC jumps in two types of fluxgates, parallel and orthogonal. We present a new model for the jumps phenomenon.

Dependence of large Barkhausen jump on length of a vicalloy fine wire with torsion stress
IEEE Transactions on Magnetics, 1998This paper concerns a magnetic sensor using a vicalloy wire with uniaxial anisotropy and torsion stress. In the magnetic sensor using a compound magnetic wire, the relationship between wire length, magnetization state and the output voltage based on the large Barkhausen jump was investigated. When the specimen wire was short, magnetizations of soft and

Large Barkhausen jumps observed in Nd-Fe-B sintered magnets at very low temperatures
IEEE Transactions on Magnetics, 1989The demagnetization process for Nd/sub 15/Fe/sub 77/B/sub 8/ sintered magnets was studied by precise loop measurements below 50 K. A zigzag variation of coercivity with temperature was observed below about 18 K. In this temperature range, the magnetization reverses with large discontinuous magnetization jumps.

The magnetization and small signal alternating-current permeabilities of transverse-field-annealed amorphous magnetostrictive wires (Fe77.5B15Si7.5) with a fixed twist of 400 deg/m were examined as a function of applied axial tensile stress and axial direct-current (dc) currents.
