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.

Restoration and Transformation: The Response of Shocked and Oxidized Magnetite to Temperature

Journal of Geophysical Research: Solid Earth, Volume 129, Issue 2, February 2024.
Abstract Large impact craters on Earth are associated with prominent magnetic anomalies, residing in magnetite of the shocked target rocks and impactites. Shock experiments on magnetite suggest that up to 90% of magnetic susceptibility is lost at pressures >5 GPa, but can be partially restored by post‐shock thermal annealing.

Magnetic Barkhausen emission in lightly deformed AISI 1070 steel

, 2012
The Magnetic Barkhausen Noise (MBN) technique can evaluate both micro- and macro-residual stresses, and provides indication about the relevance of contribution of these different stress components. MBN measurements were performed in AISI 1070 steel sheet

Influence of Magnetizing and Filtering Frequencies on Barkhausen Noise Response

IEEE Transactions on Magnetics, 2014
This paper is devoted to frequency issues of the Barkhausen noise (BN) measurements, namely, to investigation of influence of magnetizing and filtering frequencies on the BN response. The measurements were performed for typical industrial steels at controllable magnetizing conditions: fixed induction or field waveforms.
