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.

MEMS magnetic field sensor based on magnetoelectric composites

, 2022
Art. 065024, 6 S.For the measurement of biomagnetic signals in the pico- and femtotesla regime superconducting interference devices (SQUIDs) are commonly used. Their major limitation comes from helium cooling which makes these sensors bulky and expensive.

Magnetic Properties of CoFeSiB/CoNi, CoFeSiB/FeNi, FeSiB/CoNi, FeSiB/FeNi Biphase Microwires in the Temperature Range 295-1200 K

, 2015
We have studied the magnetic properties of two series of magnetically biphase microwires with 1 μm thickness of CoNi-based hard or FeNi-based soft shells with a core of FeSiB or FeCoSiB glass-coated microwires.

Computational micro-magneto-mechanics [PDF]

, 2022
We formulate a material model for micro-magneto-mechanics based on the generalized standard material approach. Our model includes exchange, elastic, anisotropy, demagnetizing and Zeeman energy.
