Giant direct and inverse magnetocaloric effect linked to the same forward martensitic transformation
(Springer Nature, 2017)
info:eu-repo/semantics/article,
Metamagnetic shape memory alloys have aroused considerable attraction as potential magnetic
refrigerants due to the large inverse magnetocaloric effect associated to the magnetic-field-induction
of a reverse martensitic ...
A comprehensive analysis of the absorption spectrum of conducting ferromagnetic wires
(IEEE, 2012)
Artículo / Artikulua,
A detailed analysis of the absorption spectrum of conductive ferromagnetic wires is presented. The absorption spectrum is computed from the solution to the scattering problem, and circuit models are formulated to clarify ...
Theoretical modeling and experimental verification of the scattering from a ferromagnetic microwire
(IEEE, 2011)
Artículo / Artikulua,
This contribution presents a theoretical modelling
of the scattering of ferromagnetic microwires in free-space and
inside a rectangular waveguide, providing both an analytical
solution and a physical interpretation of ...
Strong angular dependence of resonant states in 2D dielectric cylinder rings
(AIP Publishing, 2018)
info:eu-repo/semantics/article,
We investigate collective resonators made of dielectric cylinders assembled as two-dimensional regular octagons and decagons. These structures exhibit collective resonance states that change their intensity with the incident ...
Loss of ductility due to the decarburation and Mn depletion of a coarse-grained TWIP steel
(Consejo Superior de Investigaciones Científicas (CSIC), 2017)
info:eu-repo/semantics/article,
Se ha observado una clara transición de la ductilidad a tracción con el tamaño de grano D del orden 15 μm - 20 μm (1,50 μm ≤ D < 50 μm) en un acero TWIP, 22% de Mn, 0,6% de C (% en masa). Este comportamiento es una combinación ...
Structurally oriented nano-sheets in Co thin films: changing their anisotropic physical properties by thermally-induced relaxation
(MDPI, 2017)
info:eu-repo/semantics/article,
We show how nanocrystalline Co films formed by separated oblique nano-sheets display anisotropy in their resistivity, magnetization process, surface nano-morphology and optical transmission. After performing a heat treatment ...
Entropy change caused by martensitic transformations of ferromagnetic shape memory alloys
(MDPI, 2017)
info:eu-repo/semantics/article,
In this paper, our most recent findings on the influence of magnetic order on the main transformational caloric and elastic properties of shape memory alloys (SMAs) are reviewed. It is argued that ferromagnetic order has ...
119Sn Mössbauer spectroscopy for assessing the local stress and defect state towards the tuning of Ni-Mn-Sn alloys
(AIP Publishing, 2017)
info:eu-repo/semantics/article,
The influence of defects and local stresses on the magnetic properties and martensitic transformation in Ni50Mn35Sn15 is studied at macroscopic and atomic scale levels. We show that both the structural and magnetic properties ...
Changes in the crystalline degree in neutron irradiated EPDM viewed through infrared spectroscopy and inelastic neutron scattering
(Rede Latino-Americana de Materiais, 2018)
info:eu-repo/semantics/article,
The changes in the degree of crystallinity in commercial Ethylene Propylene Diene rubber-type M (EPDM) irradiated with neutrons at different doses has been studied by means of inelastic neutron scattering and
infrared ...
Study of the martensitic transition in Ni-Mn-Sn-Ti ferromagnetic shape memory alloys
(Rede Latino-Americana de Materiais, 2018)
info:eu-repo/semantics/article,
In the present work, mechanical spectroscopy measurements as a function of temperature and strain have been performed in (at.%) Ni50Mn37Sn13-xTix (x=0, 0.5 and 2) ferromagnetic shape memory alloys in order
both to study ...
