Studies on magnetocaloric effect of Tb2Ni0.90Si2.94 compound

, 2020
A comparative study has been carried out on the magnetocaloric properties of as-cast and annealed Tb2Ni0.90Si2.94 intermetallic compound. While the as-cast material exhibits ferromagnetic cluster-glass behaviour below 9.9 K coexisting with ...

Magnetocaloric Effect in Geometrically Frustrated Magnetic Compound HoB12

, 2010
The magnetocaloric effect of frustrated antiferromagnetic $HoB_{12}$ is calculated. The isothermal entropy change Δ S characterising the magnetocaloric effect shows a small positive change upon magnetisation below the transition temperature $T_{N ...

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

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 ...

Magnetic and Magnetocaloric Characteristics of Mixed Manganese Pnictides

Substituted MnAs0.97P0.03 manganese arsenide is prepared, and its structural, magnetic, and magnetocaloric properties are studied. At ~260 K, an abrupt decrease in the magnetization of the sample is observed, which is interpreted as a ferromagnetic ...

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.

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 ...
