A Short Review of the Magnetocaloric Effect and Selected Magnetocaloric Materials

Acta Physica Polonica A
The present paper provides a short review of the magnetocaloric effect and selected magnetocaloric materials, such as Gd-based alloys, MnCoGe alloys, and La(Fe, Si)13-type alloys. The magnetocaloric effect is a fundamental environmentally friendly technique for lowering temperature, which is nowadays highly developed due to its potential application in

Barocaloric effect in the magnetocaloric prototype Gd5Si2Ge2

Applied 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 AND MAGNETOCALORIC COOLING TECHNOLOGIES

This article analyzes the physical nature of the magnetocaloric effect and the operating principles of magnetocaloric cooling technologies based on it. The magnetocaloric effect, which is associated with temperature changes in certain ferromagnetic materials under the influence of a magnetic field, is considered a promising direction for the ...

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

Entropy, 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.

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

Magnetochemistry, 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 ...

Magnetocaloric properties of metallic nanostructures

Cogent 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

Peltier cell calorimetry “as an option” for commonplace cryostats: Application to the case of MnFe(P,Si,B) magnetocaloric materials

Fundamental Research
Peltier cell calorimetry is a powerful technique to record both the heat capacity and the latent heat, yet its availability is limited as it often requires homemade dedicated cryostats.
