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 ...
Study of optical fiber sensors for cryogenic temperature measurements
(MDPI, 2017)
info:eu-repo/semantics/article,
In this work, the performance of five different fiber optic sensors at cryogenic temperatures
has been analyzed. A photonic crystal fiber Fabry-Pérot interferometer, two Sagnac interferometers,
a commercial fiber Bragg ...
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 ...
Magnetic transition in nanocrystalline soft magnetic alloys analyzed via ac inductive techniques
(American Physical Society, 2004)
info:eu-repo/semantics/article,
The magnetic transition in a FeSiBCuNb nanocrystalline alloy, associated with the decoupling of ferromagnetic crystallites around the Curie point of the residual amorphous matrix, is analyzed in this work through the ...
Long-range atomic order and entropy change at the martensitic transformation in a Ni-Mn-In-Co metamagnetic shape memory alloy
(MDPI, 2014)
Artículo / Artikulua,
The influence of the atomic order on the martensitic transformation entropy change has been studied in a Ni-Mn-In-Co metamagnetic shape memory alloy through the evolution of the transformation temperatures under high-temperature ...
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 ...
Magnetocaloric effect enhancement driven by intrinsic defects in a Ni45Co5Mn35Sn15 alloy
(Elsevier, 2019)
info:eu-repo/semantics/article,
The influence of mechanically-induced defects on the magnetostructural properties is analyzed in a Ni-Co-Mn-Sn alloy subjected to soft milling and subsequent annealing treatments. It is found that, opposite to what occurs ...
Low field magnetic and thermal hysteresis in antiferromagnetic dysprosium
(MDPI, 2017)
Artículo / Artikulua,
Magnetic and thermal hysteresis (difference in magnetic properties on cooling and heating) have been studied in polycrystalline Dy (dysprosium) between 80 and 250 K using measurements of the reversible Villari effect and ...
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 ...
