Electronic Surveillance and Security Applications of Magnetic Microwires
(MDPI, 2021-04-30)
Applications in security and electronic surveillance require a combination of excellent magnetic softness with good mechanical and anticorrosive properties and low dimensionality. We overviewed the feasibility of using ...
Engineering of domain wall propagation in magnetic microwires with graded magnetic anisotropy
(Elsevier, 2022-03)
[EN] We report on the influence of graded magnetic anisotropy designed by stress-annealing of magnetic microwire at variable annealing temperature on domain wall propagation. We found that the domain wall propagation in a ...
Enhancing the Squareness and Bi-Phase Magnetic Switching of Co2FeSi Microwires for Sensing Application
(MDPI, 2023-05-26)
In the current study we have obtained Co2FeSi glass-coated microwires with different geometrical aspect ratios, ρ = d/Dtot (diameter of metallic nucleus, d and total diameter, Dtot). The structure and magnetic properties ...
Elucidation of the Strong Effect of the Annealing and the Magnetic Field on the Magnetic Properties of Ni2-Based Heusler Microwires
(MDPI, 2022-12-04)
We study the effect of annealing and the applied magnetic field from 50 Oe to 20 kOe on the magneto-structural behavior of Ni2FeSi-based Heusler microwires fabricated by using Taylor-Ulitovsky technique. Using the XRD ...
Soft Magnetic Amorphous Microwires for Stress and Temperature Sensory Applications
(MDPI, 2019-12)
Amorphous ferromagnetic materials in the form of microwires are of interest for the development of various sensors. This paper analyzes and argues for the use of microwires of two basic compositions of Co71Fe5B11Si10Cr3 ...
Development of Magnetic Microwires for Magnetic Sensor Applications

We observed a remarkable improvement of domain wall (DW) mobility, DW velocity, giant magnetoimpedance (GMI) effect and magnetic softening at appropriate stress-annealing conditions. Beneficial effect of stress-annealing ...
Microwire-Based Sensor Array for Measuring Wheel Loads of Vehicles
(MDPI, 2019-10-26)
In this paper, a magnetic microwire-based sensor array embedded under the pavement is proposed as a weighing system at customs ports of entry. This sensor is made of a cementitious material suitable for embedding within ...
Impact of Stress Annealing on the Magnetization Process of Amorphous and Nanocrystalline Co-Based Microwires
(MDPI, 2019-08)
The domain wall (DW) dynamics of amorphous and nanocrystalline Co-based glass-coated microwires are explored under the influence of stress annealing. Different annealing profiles have enabled remarkable changes in coercivity ...
