Enhanced cryogenic magnetocaloric effect in Eu8Ga16Ge30 clathrate nanocrystals
(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 ...

Origin of the magnetic anomaly and tunneling effect of europium on the ferromagnetic ordering in Eu8-xSrxGa16Ge30 (x = 0,4) type-I clathrates.
(American Physical Society, 2011)
Systematic dc magnetization studies using the Banerjee criterion, Kouvel-Fisher, and magnetocaloric effect methods provide physical insights into the origin of themagnetic anomaly and the tunneling effect of europium ...
