Roles of hydrogenation, annealing and field in the structure and magnetic entropy change of Tb-based bulk metallic glasses [PDF]

AIP Advances, 2013
The reduction of open-volume regions in Tb-based metallic glass (MG) by annealing and hydrogen charging was found to rearrange the atomic structure and tune the magnetic behaviors. After crystallization, the magnetic structure and magnetic entropy change

Magnetic entropy changes in nanogranular Fe:Ni61Cu39

Journal of Applied Physics, 2011
Artificial environment-friendly Gd-free magnetic nanostructures for magnetic cooling are investigated by temperature-dependent magnetic measurements. We consider two-phase nanocomposites where nanoclusters (Fe) are embedded in a Ni61Cu39 matrix. Several composite films are produced by cluster deposition.
