Peculiar magnetocaloric properties and critical behavior in antiferromagnetic Tb3Ni with complex magnetic structure
(Elsevier, 2019-08-12)
A study on the magnetocaloric properties of a Tb3Ni single crystal (which crystallizes in the orthorhombic Pnma space group) has been undertaken and combined with the study of the character and critical behavior of its ...
Study of the magnetocaloric effect in intermetallics RTX (R = Nd, Gd; T = Sc, Ti ; X = Si, Ge)
(Elsevier, 2019-05-02)
A detailed study of the magnetocaloric properties of six compounds of the intermetallic family RTX (R = Nd, Gd; T = Sc, Ti ; X = Si, Ge) has been undertaken: NdScSi, NdScGe, GdScSi, GdScGe, GdSc(Si0.5Ge0.5) and Gd(Sc0.5Ti0.5)Ge. ...
Critical behavior of the ferromagnetic transition in GdSc(Si,Ge) intermetallic compounds
(Elsevier, 2018-07-26)
A complete study on the critical behavior of the paramagnetic to ferromagnetic transition in intermetallics GdScSi, GdScGe, GdSc(Si0.5Ge0.5) and Gd(Sc0.5Ti0.5)Ge has been carried out by means of magnetic as well as ...
Critical behavior study of magnetic transitions in Dy3Co single crystals
(Elservier, 2018-02-14)
An ac photopyroelectric calorimeter has been used to study the critical behaviour of the magnetic transitions in Dy3Co measuring thermal diffusivity, specific heat and thermal conductivity, at low temperature. There are ...
Measurement of in-plane thermal diffusivity of solids moving at constant velocity using laser spot infrared thermography
(Elsevier, 2018-11-07)
In this work, an infrared thermography setup is proposed to measure the in-plane thermal diffusivity of
(an)isotropic samples that are moving at constant velocity, as it is the case of in-line production or in-line
quality ...
Thermal effusivity measurements of thermal insulators using the photopyroelectric technique in the front configuration
(Elsevier, 2018-03-21)
In the photopyroelectric (PPE) technique in the front configuration one surface of a pyroelectric sensor is illuminated by a modulated laser beam, whereas the other surface is in contact with the sample under study. A ...
Retrieving the thermal diffusivity and effusivity of solids from the same frequency scan using the front photopyroelectric technique
(IOP Science, 2017-09-14)
The photopyroelectric (PPE) technique in the front configuration consists in illuminating one
surface of a pyroelectric slab while the other surface is in contact with the test sample. This
method has been widely used ...
Measuring the thermal resistance of vertical interfaces separating two different media using infrared thermography
(Elsevier, 2019)
We propose a method to measure the thermal contact resistance at the vertical interface between two materials using lock-in infrared thermography with laser spot heating. We found an analytical expression for the surface ...
Comprehensive study of the magnetic phase transitions in Tb3Co combining thermal, magnetic and neutron diffraction measurements
(Elsevier, 2019-05-22)
A comprehensive study of the magnetic phase transitions in Tb3Co has been undertaken combining different techniques. Using single crystal neutron diffraction in the paramagnetic state a weak crystal structure distortion ...
Fast sizing of the width of infinite vertical cracks using constant velocity Flying-Spot thermography
(Elsevier, 2019-03-19)
Constant Velocity Flying-Spot thermography consists in scanning the sample surface by a focused CW-laser spot moving at constant speed. This technique was designed to study large surfaces in short times. In this work, we ...
