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 ...

Magnetocaloric effect and refrigerant capacity in Sr-doped Eu8 Ga16 Ge30 type-I clathrates
(AIP Publishing, 2010-04-19)
Magnetic properties, the magnetocaloric effect (MCE) and refrigerant capacity (RC) were investigated in Eu8Sr8−xGa16Ge30 (x=0,4) type-I clathrates. The substitution of Sr for Eu decreases the Curie temperature (TC) and ...
