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.

Influence of length and measurement geometry on magnetoimpedance in La0.7Sr0.3MnO3

, 2009
We show that ac magnetoresistance at room temperature in La0.7Sr0.3MnO3 is extremely high (= 47% in H = 100 mT, f = 3-5 MHz), and magnetic field dependence of reactance exhibits a double peak behavior.
