Optimal temperature range for determining magnetocaloric magnitudes from heat capacity
(Institute of Physics Publishing, 2016)
The determination of the magnetocaloric magnitudes (specific magnetic entropy change, Δs M, and adiabatic temperature change, ΔT ad) from heat capacity (c H) measurements requires measurements performed at very low ...

High-temperature evolution of coercivity in nanocrystalline alloys.
(American Physical Society, 2002)
The temperature evolution of the coercivity of a Finemet-type alloy, in which 10 at. % Fe has been substi- tuted by Cr and annealed at different temperatures, has been studied. In the temperature region ...

Magnetic Multilayers as a Way to Increase the Magnetic Field Responsiveness of Magnetocaloric Materials
(American Scientific Publishers, 2012)
The magnetocaloric response of Ni–Cu based multilayers has been studied with the aim of optimizing their magnetic field dependence. In contrast to the behavior of single phase materials, whose peak magnetic entropy change ...

Optimization of the refrigerant capacity in multiphase magnetocaloric materials
(AIP Publishing, 2011-03-09)
The refrigerant capacity (RC) of magnetocaloric materials can be enhanced using multiphase materials or composites, which expand the temperature range over which a significant magnetic entropy change can be obtained. ...

Nanocrystallization Kinetics Under Instantaneous Growth Approximation: Experiments and Cellular Automata Simulations
(Wiley-Blackwell, 2010)
Nanocrystallization kinetics is analyzed in the frame of instantaneous growth approximation, which implies that the time required for a crystallite to reach its final size is negligible with respect to the time required ...

Thermal stability of a supersaturated Fe-Ge-Nb solid solution produced by ball milling
(Institute of Physics Publishing (IOP), 2010)
Thermal evolution of Fe neighbourhood in a supersaturated bcc Fe(Ge,Nb) solid solution, obtained as the final product of mechanical alloying of Fe75Ge20Nb5, was studied. No changes in Fe neighbourhood were detected after ...
