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.

Universal Pulse Shape Scaling Function and Exponents: A Critical Test for Avalanche Models applied to Barkhausen Noise [PDF]
, 2001 In order to test if the universal aspects of Barkhausen noise in magnetic materials can be predicted from recent variants of the non-equilibrium zero temperature Random Field Ising Model (RFIM), we perform a quantitative study of the universal scaling ...

Hysteresis, Avalanches, and Barkhausen Noise
, 1997 Hysteresis, the lag between the force and the response, is often associated with noisy, jerky motion which have recently been called ``avalanches''. The interesting question is why the avalanches come in such a variety of sizes: naively one would expect either all small events or one large one.

Barkhausen-type noise in the resistance of antiferromagnetic Cr thin films
, 2012 We present an experimental study of the changes generated on the electrical resistance $R(T)$ of epitaxial Cr thin films by the transformation of quantized spin density wave domains as the temperature is changed. A characteristic resistance noise appears

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.
