Engineering Reports, Volume 7, Issue 1, January 2025.Barkhausen noise (BN)‐ and eddy currents (EC)‐based sensor systems were tested to detect deformation‐induced martensite during flow forming of austenitic steel 304L. The results with EC have advantages over those with BN due to the good correlation with reference α′‐martensite measurements and the low influence of factors such as roughness.

A Magnetoelastic Twist on Magnetic Noise: The Connection with Intrinsic Nonlinearities
Advanced Functional Materials, Volume 34, Issue 9, February 26, 2024.Magnetoelastic nonlinearity significantly limits the performance of devices that use ferromagnetic films as sensitive elements. By introducing a comprehensive theory of magnetic noise in sensor systems, previously unrecognized noise sources linked to magnetoelasticity are revealed.

Highly Efficient Spin Transport in a Paramagnetic Insulator at Room Temperature
Advanced Physics Research, Volume 3, Issue 2, February 2024.Efficient transmission of magnon‐mediated spin current is a crucial requirement for the development of futural spintronic devices with lower energy dissipation. The efficient spin transport in a paramagnetic insulator is demonstrated at room temperature and under a very weak magnetic field.

Research on the Orthogonal Fundamental Mode Fluxgate Sensor Circuit
IEEE Access, 2020 Currently, magnetic fluxgate circuits used for magnetic field measurements mostly adopt parallel excitation second harmonic generation. The magnetic fluxgate developed by this method cannot possess both low noise and high bandwidth at the same time.

Barkhausen Noise Analysis by Surrounding Coil [PDF]
, 1995 The Barkhausen effect (or Barkhausen noise)[1], discovered in 1919, was initially identified as the revealing of irreversible and discontinuous changes of magnetisation induced by an external magnetic field[2].
