Magnetocaloric Properties of Melt-Extracted Medium Entropy Gd₃₃Co₃₃Al₃₄ Microfibers

Metals
In this paper, a new medium entropy alloy with nominal composition of Gd33Co33Al34 was designed and fabricated into microfibers by a melt-extraction method.

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.

Compatibility of LaFe_13−x−yMn_xSi_yH_1.6 and Eutectic Liquid GaInSn Alloy

Magnetochemistry
The heat transfer rate of magnetocaloric regenerators is a topic of extensive research and the cyclability of these regenerators is critical to the operation of systems with a high coefficient of performance (e.g., potentially >22, significantly higher ...

Giant low-field magnetocaloric effect in single-crystalline EuTi0.85Nb0.15O3

APL Materials, 2016
The magnetocaloric effect in ferromagnetic single crystal EuTi0.85Nb0.15O3 has been investigated using magnetization and heat capacity measurements. EuTi0.85Nb0.15O3 undergoes a continuous ferromagnetic phase transition at TC = 9.5 K due to the long ...

Relation between 4f-magnetism and the low-temperature magnetocaloric effect in multiferroic hexagonal manganites

Communications Materials
The magnetocaloric effect enables magnetic refrigeration and plays an important role for cooling at cryogenic temperatures, which is essential for emergent technologies such as hydrogen liquefaction and quantum computing. Here, we study the origin of the

Large magnetocaloric effect in Gd4Co3

, 2007
We report a large entropy change (DeltaS) below 300 K, peaking near TC= 220 K, due to isothermal change of magnetic field, for Gd4Co3, with a refrigeration capacity higher than that of Gd. Notably, the isothermal magnetization is nonhysteretic - an important criterion for magnetic refrigeration without loss.
