Effect of the valence state on the band magnetocrystalline anisotropy in two-dimensional rare-earth/noble-metal compounds
(American Physical Society, 2022)
[EN] In intermetallic compounds with zero orbital momentum (L = 0) the magnetic anisotropy and the electronic band structure are interconnected. Here, we investigate this connection in divalent Eu and trivalent Gd intermetallic ...
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 ...
Ni-Mn-Sn-Cu Alloys after Thermal Cycling: Thermal and Magnetic Response
(MDPI, 2021-11-13)
Heusler Ni-Mn-Sn-based alloys are good candidates for magnetic refrigeration. This application is based on cycling processes. In this work, thermal cycles (100) have been performed in three ribbons produced by melt-spinning ...
Sustainable PHBH–Alumina Nanowire Nanocomposites: Properties and Life Cycle Assessment
(MDPI, 2022-11-20)
Poly(3-hydroxybutyrate-co-3-hydroxyhexanoate) (PHBH) is a bio-based polyester with the potential to replace some common polymers of fossil origin. However, PHBH presents serious limitations, such as low stiffness, tendency ...
Fabrication and Magneto-Structural Properties of Co2-Based Heusler Alloy Glass-Coated Microwires with High Curie Temperature
(MDPI, 2022)
[EN] In this work, we were able to produce Co2FeSi Heusler alloy glass-covered microwires with a metallic nucleus diameter of about 4.4 µm and total sample diameter of about 17.6 μm by the Taylor–Ulitovsky Technique. This ...
Development of Magnetically Soft Amorphous Microwires for Technological Applications
(MDPI, 2022-01-07)
Amorphous magnetic microwires can be suitable for a variety of technological applications due to their excellent magnetic softness and giant magnetoimpedance (GMI) effect. Several approaches for optimization of soft magnetic ...
Development of Co-Rich Microwires with Graded Magnetic Anisotropy
(MDPI, 2021-12-28)
In this paper, a gradual change in the hysteresis loop of Co-rich glass-coated microwire stress-annealed at variable temperature is observed. Such microwires annealed with a temperature gradient also present a variable ...
Tuning of Magnetoimpedance Effect and Magnetic Properties of Fe-Rich Glass-Coated Microwires by Joule Heating
(MDPI, 2022-01-29)
The influence of Joule heating on magnetic properties, giant magnetoimpedance (GMI) effect and domain wall (DW) dynamics of Fe75B9Si12C4 glass-coated microwires was studied. A remarkable (up to an order of magnitude) ...
Lignin solvation by ionic liquids: The role of cation
(Elsevier, 2020-01-30)
The use of ionic liquids as solvents for the processing of lignocellulosic material has received considerable attention in the last years, since it presents remarkable advantages over previous solvent-based procedures. In ...
