Magnetoimpedance of metallic ferromagnetic wires

Physical Review B, 1998
The ac impedance $Z=R+j\ensuremath{\omega}L$ of a metallic soft magnetic wire with periodic circular domains relevant to domain-wall displacements is calculated and compared with the classical model relevant to domain magnetization rotations (DMR). It is shown that the magnetoimpedance (MI) defined as the relative change of $|Z|$ with a longitudinal dc

Giant magnetoimpedance and inductance spectroscopy

Journal of Alloys and Compounds, 2004
A brief review of the giant magnetoimpedance (GMI) phenomenon is presented, including the general definition and phenomenology. The change from impedance modulus to complex inductance is presented, which allows a clearer view of the physics involved.

Effect of nanocrystallization on Giant magnetoimpedance effect of microwires

2013 Seventh International Conference on Sensing Technology (ICST), 2013
We studied GMI effect and magnetic properties of Finemet-type FeCuNbSiB microwires. We observed that GMI magnetic field and frequency dependences and magnetic softness of composite microwires produced by the Taylor-Ulitovski technique can be tailored either controlling magnetoelastic anisotropy of as-prepared FeCuNbSiB microwires or controlling their ...

Coupled core–shell model of magnetoimpedance in wires

Journal of Applied Physics, 2004
Magnetoimpedance (MI) has been studied extensively in soft magnetic wires and plates. Although a general theoretical basis has evolved, several details remain poorly understood. In particular, the amplitude of the effect in the low field region has proven impossible to fit within current models which assume a uniform static magnetization within the ...

An integrated giant magnetoimpedance biosensor for detection of biomarker

Biosensors and Bioelectronics, 2014
A Dynabeads-labeled magnetic immunoassay (MIA) has been developed by using an integrated giant magnetoimpedance (GMI) biosensor for the detection of alpha-fetoprotein (AFP). The GMI biosensor (Cr/Cu/NiFe/Cu/NiFe/Al2O3/Cr/Au films) integrated magnetic sensing elements and a biomolecular immunoplatform.

Microwave Magnetoimpedance of Superconducting Tin

Physical Review, 1964
Measurements, using a bimodal cavity, of the temperature and magnetic field dependence of the surface impedance of a single crystal of superconducting tin at a frequency of 23.5 Gc/sec are reported. In the geometry used, the static and microwave magnetic fields were parallel over the surface of the sample. The temperature dependence of the reactance in
