摘要	Nanocapsules with the intermetallic compound Ce3Al11 as core and amorphous Al2O3 (or Al) as the shell have been prepared using the arc-discharge technique. The Ce3Al11/Al2O3 nanocapsules display superparamagnetic properties between the blocking temperature and the Curie temperature. The cryogenic magnetocaloric effect of the Ce3Al11/Al2O3 nanocapsules was measured between 2 and 14 K. A maximum magnetic-entropy change -Delta S-M of 8.3 J kg(-1) K-1 has been observed at 4.5 K for a magnetic-field change from 0 to 70 kOe. (C) 2008 Elsevier B.V. All rights reserved.
