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

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 ...

Anisotropic magnetocaloric effect in nanostructured magnetic clusters

, 2001
We report the first experimental observation of anisotropic magnetocaloric effect (MCE) in the Fe8lusters. It is found that the magnetic anisotropy plays a very important role in the determination of the magnetocaloric effect. The maximum and minimum MCE'

Contribution of entropy changes to the inverse magnetocaloric effect for Ni46.7Co5Mn33In15.3 Heusler alloy

, 2015
In this paper, the changes of volume fractions between austenitic and martensitic phase have been carefully deduced through magnetization data for polycrystalline Ni46.7Co5Mn33In15.3 alloy during reverse martensitic transformation at different magnetic ...
