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. ...
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 ...
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 ...
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 ...
Review of Domain Wall Dynamics Engineering in Magnetic Microwires
(MDPI, 2020-12-01)
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 ...
Functionalization of particles by atomic layer deposition for energy storage applications
(2020-02-18)
Los materiales en forma de pequeñas partículas son uno de los principales ingredientes en diversos procesos y aplicaciones industriales, gracias a sus relevantes propiedades con relación a su combinación de pequeño tamaño ...
Ferritin-based hybrid nanocomposites for enzyme-mimetic catalytic activity
(2017-09-13)
In this thesis natural and synthetic hybrid ferritin are studied from three different perspectives:The catalytic activity of platinum nanoparticle-apoferritin nanocomposites is characterized focusing onthe catalase and ...
