Barocaloric effect in the magnetocaloric prototype Gd5Si2Ge2

open access: yesApplied Physics Letters, 2012
We report on calorimetric measurements under hydrostatic pressure that enabled us to determine the barocaloric effect in Gd5Si2Ge2. The values for the entropy change for moderate pressures compare favourably to those corresponding to the magnetocaloric effect in this compound.

Magnetocaloric Effect in an Antidot: The Effect of the Aharonov-Bohm Flux and Antidot Radius

open access: yesEntropy, 2018
In this work, we report the magnetocaloric effect (MCE) for an electron interacting with an antidot, under the effect of an Aharonov-Bohm flux (AB-flux) subjected to a parabolic confinement potential.

Controllable spin-glass behavior and large magnetocaloric effect in Gd-Ni-Al bulk metallic glasses

open access: yes, 2012
Glass-forming ability, spin-glass (SG) behavior, and magnetocaloric effect in Gd55NixAl45-x (x?15, 20, 25, 30) metallic alloys were investigated. A ferromagnetic SG behavior was observed for glassy ribbons with compositions of x?15, 20, and 25, but it ...

Tunable magnetocaloric effect in RTi

open access: yes, 2007
The tetragonal layered compounds TbTiGe and ErTiGe order antiferromagnetically at 276 K and 39 K, respectively. Partial substitution of Mo for Ti in these two compounds modifies the magnetic interactions giving rise to a ferromagnetic ground state ...

Co doping enhanced giant magnetocaloric effect in Mn1-xCoxAs films epitaxied on GaAs (001)

open access: yes, 2010
A giant magnetocaloric effect was found in series of Mn1-xCoxAs films epitaxied on GaAs (001). The maximum magnetic entropy change caused by a magnetic field of 4 T is as large as 25 J/kg K around room temperature, which is about twice the value of pure ...

Magnetocaloric Effect in $NdNi_4Si$ Compound

open access: yes, 2012
On the basis of the thermodynamic approach, we report the magnetocaloric properties of the ternary ferromagnetic $NdNi_4Si$ compound with magnetic phase transition temperature $T_{C}$ at 8 K. The saturated magnetic moment in H = 9 T is equal to 1.5 $μ_{B}

Magnetocaloric properties of metallic nanostructures

open access: yesCogent Engineering, 2015
A compilation of magnetocaloric properties of metallic nanostructures with Curie temperature (TC) between 260 and 340 K has been tabulated. The tabulated data show that nanostructure plays an important role in enhancing the magnetocaloric properties of a

Effect of Quenching and Normalizing on the Microstructure and Magnetocaloric Effect of a Cu–11Al–9Zn Alloy with 6.5 wt % Ni–2.5 wt % Fe

open access: yesMagnetochemistry, 2019
First-order phase transitions (FOPT) and second-order phase transitions (SOPT) are commonly observed in Cu alloys containing lanthanide elements, due to their electronic configuration, and have an important effect on the optimization of their ...
