Marín Palacios, María Pilar ; Aragón, A. M ; Garcia Escoria, A. ; Lieblich, M. ; Crespo del Arco, Patricia ; Hernando Grande, Antonio | American Institute of Physics | 2013-01-28Fe_(73.5)Si_(13.5)B_9Nb_3Cu_1 powder particles have been obtained by gas atomization. Magnetization curves and coercivity were studied for particles ranging in size up to 1000?. The overall magnetic behavior of such material is consequence of c[...]texto impreso
Morales Casero, Irene ; Archilla Sanz, Diego ; Presa Muñoz del Toro, Patricia de la ; Hernando Grande, Antonio ; Marín Palacios, María Pilar | Nature Publishing Group | 2020-01-17It is well stablished that heating efficiency of magnetic nanoparticles under radiofrequency fields is due to the hysteresis power losses. In the case of microwires (MWs), it is not clear at all since they undergo non-coherent reversal mechanism[...]texto impreso
Birame Gueye, Papa Gorgui ; López Sánchez, Jesús ; Navarro Palma, Elena ; Serrano, Aída ; Marín Palacios, María Pilar | American Chemical Society | 2020-04-01A combination of high-energy ball milling, vacuum filtering, and sedimentation processes has been demonstrated to be a useful approach to reduce, in a controlled way, the length of as-cast Fe_(73.5)Si_(13.5)Nb_3Cu_1B_9 amorphous magnetic microwi[...]texto impreso
Prato, Rafael A ; Van Vught, Vincent ; Eggermont, Sam ; Pozo, Guillermo ; Marín Palacios, María Pilar ; Fransaer, Jan ; Dominguez-Benetton, Xochitl | Nature Publishing Group | 2019-10-25The electrosynthesis of iron oxide nanoparticles offers a green route, with significant energy and environmental advantages. Yet, this is mostly restricted by the oxygen solubility in the electrolyte. Gas-diffusion electrodes (GDEs) can be used [...]texto impreso
Marín Palacios, María Pilar ; Marcos, M. ; Hernando Grande, Antonio | American Institute of Physics | 2010-06-28In this letter, we report the experimental work carried out to study and improve the magnetomechanical coupling on magnetic microwires. A good magnetoelastic response, with magnetoelastic coupling factor k=0.43, has been obtained by control of b[...]texto impreso
Cobos Fernández, Miguel Ángel ; Presa Muñoz del Toro, Patricia de la ; Llorente, I. ; Alonso Rodríguez, José María ; Garcia Escorial, A. ; Marín Palacios, María Pilar ; Hernando Grande, Antonio ; Jiménez, J. A. | American Chemical Society | 2019-07-18Magnetic properties of spinel zinc ferrites are strongly linked to the synthesis method and the processing route since they control the microstructure of the resulting material. In this work, ZnFe_2O_4 nanoparticles were synthesized by the mecha[...]texto impreso
Presa Muñoz de Toro, Patricia De la ; Marín Palacios, María Pilar ; Hernando Grande, Antonio ; Spottorno Giner, Jorge ; Cobos Fernández, Miguel Ángel ; Morales Casero, Irene ; Archilla Sanz, Diego ; Giacomone, Luis Fernando | 2018-10-16Este proyecto persigue un doble objetivo. Por un lado, por medio de acciones formativas específicas, facilitar al personal docente de secundaria y bachillerato los medios para el montaje y realización de experimentos sencillos de bajo coste, que[...]texto impreso
Moya, Alberto ; Archilla Sanz, Diego ; Navarro Palma, Elena ; Hernando Grande, Antonio ; Marín Palacios, María Pilar | MDPI | 2019-07-12Co-based amorphous microwires presenting the giant magnetoimpedance effect are proposed as sensing elements for high sensitivity biosensors. In this work we report an experimental method for contactless detection of stress, temperature, and liqu[...]texto impreso
López Sánchez, Jesús ; Marín Palacios, María Pilar ; Carmona Tejero, Noemi ; Rodríguez de la Fuente, Óscar ; Serrano, A. ; Campo, A. del ; Abuín, M. ; Salas Colera, E. ; Muñoz Noval, A: ; Castro, G. R. | Royal Society Chemical | 2019-06-09The purpose of this work is to fabricate self-assembled microstructures by the sol-gel method and study the morphological, structural and compositional dependence of epsilon-Fe_2O_3 nanoparticles embedded in silica when glycerol (GLY) and cetyl-[...]texto impreso
Pozo, Guillermo ; Presa Muñoz del Toro, Patricia de la ; Prato, Rafael ; Morales Casero, Irene ; Marín Palacios, María Pilar ; Fransaer, Jan ; Dominguez-Benetton, Xochitl | Royal Society of Chemistry | 2020-03-07Materials displaying novel magnetic ground states signify the most exciting prospects for nanoscopic devices for nanoelectronics and spintronics. Spin transition materials, e.g., spin liquids and spin glasses, are at the forefront of this pursui[...]texto impreso
Herrero Gómez, Carlos ; Aragón Sánchez, Ana María ; Hernando Rydings, Manuel ; Marín Palacios, María Pilar | American Institute of Physics | 2014-09-01In this paper, we report an experimental study on the microwave modulated scattering intensity for a single Fe_2.25Co_72.75Si_10B_15 amorphous metallic microwire. The modulation is driven by applying a bias magnetic field that tunes the magnetic[...]texto impreso
Lopez-Dominguez, V. ; García, M. A. ; Marín Palacios, María Pilar ; Hernando Grande, Antonio | Nature Publishing Group | 2017-07-24In this work, we demonstrate theoretically and experimentally the possibility of tuning the electromagnetic properties of metamaterials with magnetic fields by incorporating amorphous magnetic microwires. The large permeability of these wires at[...]
