Helical magnetic structures in magnetostrictive amorphous microwires

Physica B: Condensed Matter, 2020
Surface magnetic structures have been studied in amorphous glass-covered microwires using the magneto-optical technique. Different types of helical structure have been recognized depending on the external conditions.

Heat and current annealing effects on magnetic properties of Fe-rich glass-coated amorphous microwires with different radius

2023 IEEE International Magnetic Conference - Short Papers (INTERMAG Short Papers), 2023
For Fe-rich glass-coated microwires to be a competitive option for magnetic technologies, the enhancing and tuning of their properties is necessary, and therefore, a better understanding of these processes is also needed.

Metamaterials from Amorphous Ferromagnetic Microwires: Interaction between Microwires

Solid State Phenomena, 2009
For inhomogeneous mediums the оptical Magnus effect has been derived. The metamaterials fabricated from amorphous ferromagnet Co-Fe-Cr-B-Si microwires are shown to exhibit a negative refractive index for electromagnetic waves over wide scale of GHz frequencies.

Dynamic hysteresis in magnetostrictive amorphous microwires

IEEE Transactions on Magnetics, 2002
Summary form only given. Amorphous magnetostrictive wires exhibit very rapid bistable magnetisation reversal (large Barkhausen jump). This property makes them unique for applications in security sensors and pulse generators. As operational frequencies become progressively higher, there is an interest in studying the magnetisation reversal in bistable ...

Amorphous microwires in microwave fields

Fourth International Kharkov Symposium 'Physics and Engineering of Millimeter and Sub-Millimeter Waves'. Symposium Proceedings (Cat. No.01EX429), 2002
The results of ferromagnetic resonance measurements for microwires in the 75 GHz and 10 GHz frequency bands over a wide temperature range (300 K-0.5 K) are presented. Discussion and analysis of the magnetospectroscopy results are given in the paper. The possible reasons for the magnetoimpedance jump revealed in the vicinity of the low-field area are ...

Magnetoelastic anisotropy of amorphous microwires

Journal of Magnetism and Magnetic Materials, 2003
Anisotropy constants of amorphous microwires with positive, negative, and nearly zero magnetostriction, are calculated as function of wire dimensions starting from the distribution of internal stresses induced during preparation. Some basic aspects of their magnetic behavior are subsequently discussed, in correlation with earlier experimental results.

Dipolar Interaction Between Amorphous Microwires

IEEE Transactions on Magnetics, 2008
We present a model for the description of the magnetostatic interaction between two glass-coated amorphous microwires with positive magnetostriction. We report the results of dipolar field calculations based on this model as well as results of measurements on microwires with their ends separated.

Explosive transition in amorphous microwire

Technical Physics, 2017
An amorphous microwire in a glass shell offers a quick thermal response and can be rapidly heated to the crystallization point. When heated by a current pulse with a small amplitude and duration, the wire passes from the amorphous to microcrystalline state.

Temperature Dependence of Magnetization Reversal and Harmonic Spectrum in Low Curie Temperature Amorphous Microwires

IEEE Magnetics Letters
The present study focuses on the investigation of the magnetization reversal process in amorphous microwires of the composition Co64.82Fe3.9B10.2Si12Cr9Mo0.08, which possesses a low Curie temperature ${{T}_c}$ of 61 °$\mathrm{C}$. The microwire retains a
