Magnetization Reversal Modes in Short Nanotubes with Chiral Vortex DomainWalls
(MDPI, 2018-01-10)
Micromagnetic simulations of magnetization reversal were performed for magnetic nanotubes of a finite length, L, equal to 1 and 2 mum, 50 and 100 nm radii, R, and uniaxial anisotropy with "easy axis" parallel to the tube ...
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 ...
Characterisation of Exposure to Non-Ionising Electromagnetic Fields in the Spanish INMA Birth Cohort: Study Protocol
(Biomed Central, 2016-02-18)
Background: Analysis of the association between exposure to electromagnetic fields of non-ionising radiation (EMF-NIR) and health in children and adolescents is hindered by the limited availability of data, mainly due to ...
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 ...
Magnetic properties of “thick” glass-coated Fe-rich microwires
(American Institute of Physics, 2019-03)
We report on preparation and magnetic properties of Fe71.7B13.4Si11Nb3Ni0.9 glass-coated microwire with metallic nucleus diameter d = 103 mu m and total diameter D = 158 mu m prepared by Taylor-Ulitovsky method. Amorphous ...
Coercivity and Magnetic Anisotropy of (Fe0.76Si0.09B0.10P0.05)97.5Nb2.0Cu0.5 Amorphous and Nanocrystalline Alloy Produced by Gas Atomization Process
(MDPI, 2020-05-04)
We present the evolution of magnetic anisotropy obtained from the magnetization curve of (Fe0.76Si0.09B0.10P0.05)97.5Nb2.0Cu0.5 amorphous and nanocrystalline alloy produced by a gas atomization process. The material obtained ...
Domain walls collision in Fe-rich and Co-rich glass covered microwires
(EDP Sciences, 2013-01)
We report the results of the investigation of domain walls propagation in Fe-rich and Co-rich microwires performed using Sixtus-Tonks and magneto-optical Kerr effect techniques. It was found that under certain experimental ...
