Tunable asymmetric magnetoimpedance effect in ferromagnetic NiFe/Cu/Co films

, 2014
We investigate the magnetization dynamics through the magnetoimpedance effect in ferromagnetic NiFe/Cu/Co films. We observe that the magnetoimpedance response is dependent on the thickness of the non-magnetic Cu spacer material, a fact associated to the ...

Current distribution and giant magnetoimpedance in composite wires with helical magnetic anisotropy

, 2005
The giant magnetoimpedance effect in composite wires consising of a non-magnetic inner core and soft magnetic shell is studied theoretically. It is assumed that the magnetic shell has a helical anisotropy.

Giant magnetoimpedance: new electrochemical option to monitor surface effects?

, 2006
Magnetoimpedance, MI, change due to surface modification of the sensitive element caused by biofluids was studied with the aim of creating a robust sensor capable of separating the chemical surface modification from the sensing process.

Estimation of the frequency and magnetic field dependence of the skin depth in Co-rich magnetic microwires from GMI experiments

Journal of Science: Advanced Materials and Devices, 2016
We studied giant magnetoimpedance (GMI) effect in magnetically soft amorphous Co-rich microwires in the extended frequency range. From obtained experimentally dependences of the GMI ratio on magnetic field at different frequencies we estimated the ...

Modeling of torsion stress giant magnetoimpedance in amorphous wires with negative magnetostriction

, 2007
A model describing the influence of torsion stress on the giant magnetoimpedance in amorphous wires with negative magnetostriction is proposed. The wire impedance is found by means of the solution of Maxwell equations together with the Landau-Lifshitz ...

Operation Regimes and Design Principles of Delta‐E Effect Sensors

Advanced Sensor Research, Volume 5, Issue 4, April 2026.
Delta‐E effect magnetoelectric sensors enable the detection of weak magnetic fields, yet performance optimization remains nontrivial due to coupled magnetic, mechanical, and electronic losses. A systematic study of 24 miniaturized MEMS devices with different geometries reveals three excitation‐dependent regimes: electronic‐noise, magnetic‐noise, and ...
