Magnetic Structure of Wiegand Wire Analyzed by First-Order Reversal Curves [PDF]
Materials, 2022 Various coercive force field components in Wiegand wire exhibit a significant magnetization reversal under an applied magnetic field. A fast magnetization reversal is accompanied by a large Barkhausen jump, which induces a pulse voltage in a pickup coil wound around the Wiegand wire which serves as a power source for the devices or sensors.

Magnetic Reversal in Wiegand Wires Evaluated by First-Order Reversal Curves [PDF]
Materials, 2021 The magnetic structure of Wiegand wires cannot be evaluated using conventional magnetization hysteresis curves. We analyzed the magnetization reversal of a Wiegand wire by measuring the first-order reversal curves (FORCs). A FeCoV Wiegand wire with a magnetically soft outer layer and a hard magnetic core was used in this study.
