Trasformación martensítica y efecto magnetocalórico en aleaciones Ni50Mn37Sn13 y MnCoGeBx obtenida por enfriamiento rapido.
(2014)
"La presente tesis está orientada al estudio de la transformación martensítica (TM) y el efecto magnetocalórico de aleaciones Ni50Mn37Sn13 y Mn0.96Co1.04GeB0.02. Como aspecto complementario se incluye un capítulo en el que ...
Magnetostructural transition and magnetocaloric effect in MnNiGe1.05 melt-spun ribbons
(2014-05)
"Alloy ribbons of nominal composition MnNiGe1.05 were produced using the melt-spinning technique. As-quenched (aq) polycrystalline ribbons are single-phase showing the hexagonal Ni2In-type crystal structure. After thermal ...
Expanded use of a fast photography technique to characterize laser-induced plasma plumes
(2014-06)
"Expanded use of fast photography is proposed to characterize laser ablation plasma plumes by the analysis of a set of photographs by means of appropriate mathematical algorithms. The laser ablation plasma plumes studied ...
Microstructure and composition design of magnetic Ni-Mn-Sn Co-sputter deposited films
(2015)
"In this work, we study the effect of the substrate temperature (ST) during sputter-deposition as well as co-sputtering deposition on the fabrication of nanostructured Ni-Mn-Sn thin films. Sputtered films show Mn losses ...
Enhanced magnetocaloric effect tuning efficiency in Ni-Mn-Sn alloy ribbons
(Elsevier B.V., 2017-11)
"The present work was undertaken to investigate the effect of microstructure on the magnetic entropy change of Ni50Mn37Sn13 ribbon alloys. Unchanged sample composition and cell parameter of austenite allowed us to study ...
Transformation behavior and magnetocaloric effect in Mn1−xCrxCoGe (x = 0.04 and 0.11) melt-spun ribbons tailored by heat treatment
(Elsevier, 2017-12)
"Recently, MnNiGe and MnCoGe intermetallic compounds have received a considerable attention due to the coupled tunable martensitic and magnetic transitions as well as giant magnetocaloric effect (MCE) they exhibit. In this ...
On the correct estimation of the magnetic entropy change across the magneto-structural transition from the Maxwell relation: study of MnCoGeBx alloy ribbons
(Elsevier, 2017)
"An accurate calculation of the different magnetocaloric-related magnitudes derived from the temperature dependence of the magnetic entropy change in materials exhibiting first-order magnetocaloric effect is imperative to ...
