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.

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.

Modeling of asymmetric giant magnetoimpedance in amorphous ribbons with a surface crystalline layer
, 2005 A model describing the asymmetric giant magnetoimpedance (GMI) in field-annealed amorphous ribbons is proposed. It is assumed that the ribbon consists of an inner amorphous core and surface hard magnetic crystalline layers.

Fluxgate: Tuned vs. Untuned Output [PDF]
, 1998 Fluxgate voltage output contains information about the measured DC magnetic field in amplitude of even harmonic components. Tuning the sensor output causes the concentration of output energy to specific harmonics (usually 2f) and parametric amplification.
