Magnetic Characterization in the Rayleigh Region of Nanocrystalline Magnetic Cores
(MDPI, 2018-11-14)
We report on the structural and magnetic characterization of two nanocrystalline Finemet-type magnetic cores. The nanocrystalline structure developed after annealing the amorphous precursor alloy at 550 degrees C for 30 ...
Development of Magnetic Microwires for Magnetic Sensor Applications
(MDPI, 2019-11-02)
Thin magnetic wires can present excellent soft magnetic properties (with coercivities up to 4 A/m), Giant Magneto-impedance effect, GMI, or rectangular hysteresis loops combined with quite fast domain wall, DW, propagation. ...
Optimization of magnetic properties and GMI effect of Thin Co-rich Microwires for GMI Microsensors
(MDPI, 2020-03-11)
Magnetic microwires can present excellent soft magnetic properties and a giant magnetoimpedance effect. In this paper, we present our last results on the effect of postprocessing allowing optimization of the magnetoimpedance ...
Engineering of Magnetic Softness and Domain Wall Dynamics of Fe-rich Amorphous Microwires by Stress- induced Magnetic Anisotropy
(Nature Publishing, 2019-08-27)
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 ...
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 ...
Review of Domain Wall Dynamics Engineering in Magnetic Microwires

The influence of magnetic anisotropy, post-processing conditions, and defects on the domain wall (DW) dynamics of amorphous and nanocrystalline Fe-, Ni-, and Co-rich microwires with spontaneous and annealing-induced magnetic ...
Magnetic Microwires with Unique Combination of Magnetic Properties Suitable for Various Magnetic Sensor Applications
(MDPI, 2020-12-16)
There is a pressing demand to improve the performance of cost-effective soft magnetic materials for use in high performance sensors and devices. Giant Magneto-impedance effect (GMI), or fast single domain wall (DW) propagation ...
Optimization of Magnetic Properties of Magnetic Microwires by Post-Processing
(MDPI, 2020-08-18)
The influence of post-processing conditions on the magnetic properties of amorphous and nanocrystalline microwires has been thoroughly analyzed, paying attention to the influence of magnetoelastic, induced and magnetocrystalline ...
Magnetoimpedance Response and Field Sensitivity in Stress-Annealed Co-Based Microwires for Sensor Applications
(MDPI, 2020-06-05)
Amorphous soft magnetic microwires have attracted much attention in the area of sensor applications due to their excellent properties. In this work, we study the influence of annealing treatments (stress and conventional) ...
Manipulation of domain wall dynamics in amorphous microwires through the magnetoelastic anisotropy
(Springer, 2012-04)
We studied the effect of magnetoelastic anisotropy on domain wall (DW) dynamics and remagnetization process of magnetically bistable Fe-Co-rich microwires with metallic nucleus diameters (from 1.4 to 22 mu m). We manipulated ...
