Anomalous Magnetic Anisotropy Behaviour in Co-Rich and Fe-Rich Glass-Coated Microwires under Applied Stress
; Blanco Aranguren, Juan María
; Corte León, Paula ; ; ; González Estévez, Julián María ; Zhukov Egorova, Arkady Pavlovich ; Zhukova Zhukova, Valentina (MDPI, 2023-09-25)
In this article, we study the effect of annealing temperature and applied stress on the magnetic properties of Fe71.80B13.27Si11.02Nb2.99Ni0.92 and Co65.34Si12.00B10.20Cr8.48Fe3.90Mo0.08 microwires. An anomalous behavior ... -
Carbon-Doped Co2MnSi Heusler Alloy Microwires with Improved Thermal Characteristics of Magnetization for Multifunctional Applications
; ; ; Zhukova Zhukova, Valentina; Zhukov Egorova, Arkady Pavlovich (MDPI, 2023-07-29)
In the current work, we illustrate the effect of adding a small amount of carbon to very common Co2MnSi Heusler alloy-based glass-coated microwires. A significant change in the magnetic and structure structural properties ... -
Monitoring the Velocity of Domain Wall Motion in Magnetic Microwires
; Corte León, Paula; Zhukova Zhukova, Valentina ; Blanco Aranguren, Juan María ; Zhukov Egorova, Arkady Pavlovich (MDPI, 2024-02-19)
An approach was proposed to control the displacement of domain walls in magnetic microwires, which are employed in magnetic sensors. The velocity of the domain wall can be altered by the interaction of two magnetic microwires ... -
Optimization of Magnetoimpedance Effect and Magnetic Properties of Fe-Rich Glass-Coated Microwires by Annealing
; ; Zhukova Zhukova, Valentina; Corte León, Paula ; ; Blanco Aranguren, Juan María ; González Estévez, Julián María ; (MDPI, 2023-08-28)
As-prepared Fe-rich microwires with perfectly rectangular hysteresis loops present magnetization reversal through fast domain wall propagation, while the giant magnetoimpedance (GMI) effect in Fe-rich microwires is rather ... -
Role of Eu2+ and Dy3+ Concentration in the Persistent Luminescence of Sr2MgSi2O7 Glass-Ceramics
Fernández-Rodríguez, Laura; Balda de la Cruz, Rolindes; Fernández Rodríguez, Joaquín Manuel; Durán, Alicia; Pascual, María Jesús (MDPI, 2022-04-22)
In this study, glass-ceramics based on Sr2MgSi2O7 phosphor co-doped with Eu/Dy were obtained from the sintering and crystallisation of glass powders. The glasses were melted in a gas furnace to simulate an industrial ... -
Sustainable Sheep Wool/Soy Protein Biocomposites for Sound Absorption
; ; Guerrero Manso, Pedro Manuel; De la Caba Ciriza, María Coro (MDPI, 2022-12-01)
The wool fibers of the Latxa sheep breed were combined with a soy protein isolate (SPI) matrix to develop sustainable biocomposites with acoustic properties, adding value to Latxa sheep wool, which is currently considered ... -
Temperature Dependence of the Hyperfine Magnetic Field at Fe Sites in Ba-Doped BiFeO3 Thin Films Studied by Emission Mössbauer Spectroscopy
; ; ; ; ; ; ; ; ; ; ; Unzueta Solozabal, Iraultza; ; ; ; ; ; ; ; ; (MDPI, 2023-04-25)
Emission 57Fe Mössbauer spectroscopy (eMS), following the implantation of radioactive 57Mn+ ions, has been used to study the temperature dependence of the hyperfine magnetic field at Fe sites in Ba-doped BiFeO3 (BFO) thin ... -
The Magnetostriction of Amorphous Magnetic Microwires: The Role of the Local Atomic Environment and Internal Stresses Relaxation
Zhukova Zhukova, Valentina; ; ; ; ; Corte León, Paula ; ; ; Zhukov Egorova, Arkady Pavlovich (MDPI, 2023-10-20)
We studied the magnetostriction coefficients, λs, Curie temperature, Tc, and their dependence on annealing conditions in Fe47Ni27Si11B13C2 and Co67Fe3.9Ni1.5B11.5Si14.5Mo1.6 amorphous glass-coated microwires with rather ... -
Unveiling the Magnetic and Structural Properties of (X2YZ; X = Co and Ni, Y = Fe and Mn, and Z = Si) Full-Heusler Alloy Microwires with Fixed Geometrical Parameters
; Zhukova Zhukova, Valentina; ; Zhukov Egorova, Arkady Pavlovich (MDPI, 2023-10-29)
We studied Ni2FeSi-, Co2FeSi-, and Co2MnSi-based full-Heusler alloy glass-coated microwires with the same geometric parameters, i.e., fixed nucleus and total diameters, prepared using the Taylor–Ulitovsky method. The ...
