The effect of distributed exchange parameters on magnetocaloric refrigeration capacity in amorphous and nanocomposite materials [Article]
(AIP Publishing, 2012-02-17)
The temperature dependent magnetization of nanocomposite alloys has been fit with a modified Handrich-Kobe equation with an asymmetric exchange fluctuation parameter combined with the Arrott-Noakes equation. The two equations ...
Magnetocaloric response of Fe75Nb10B15Fe75Nb10B15 powders partially amorphized by ball milling [Article]
(AIP Publishing, 2009)
The magnetocaloric response of mechanically alloyed Fe75Nb10B15 powders was studied for samples with different amorphous and nanocrystal volume fractions. Thermomagnetic properties scale following a 3 law for different ...
Enhanced cryogenic magnetocaloric effect in Eu8Ga16Ge30 clathrate nanocrystals [Article]
(AIP Publishing, 2015)
We observe an enhanced magnetic entropy change ( D S M ) at cryogenic temperatures (T < 20 K) in Eu 8 Ga 16 Ge 30 clathrate (type-I) nanocrystals prepared by a ball milling method. With reduction in the ...
Influence of Mn on the magnetocaloric effect of nanoperm-type alloys [Article]
(AIP Publishing, 2010)
In this paper, the influence of the Mn content on the magnetocaloric response of ribbon-shaped amorphous samples of Fe80−xMnxB20 x=10, 15, 18, 20, and 24 , has been studied. For this purpose, the temperature and field ...
