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 ...
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 ...
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 ...
Interferometric vs wavelength selective optical fiber sensors for cryogenic temperature measurements
(SPIE, 2017)
info:eu-repo/semantics/conferenceObject,
In this work, a preliminary study of the behavior of two different interferometric fiber optic sensors and two different wavelength selective fiber optic sensors is performed. A photonic cristal fiber Fabry-Pérot interferometer, ...
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 ...
