Magnetic materials and devices for the 21st century: Stronger, lighter, and more energy efficient

Oliver Gutfleisch, +5 more
- 15 Feb 2011 - 
TL;DR: Considering future bottlenecks in raw materials, options for the recycling of rare-earth intermetallics for hard magnets will be discussed and their potential impact on energy efficiency is discussed.
Journal ArticleDOI

Giant magnetocaloric effect driven by structural transitions

Jian Liu, +4 more
- 01 Jul 2012 - 
TL;DR: A phenomenological model is established that reveals the parameters essential for such a large adiabatic temperature change ΔT(ad), and it is demonstrated that obstacles to the application of Heusler alloys can be overcome by using the multi-response to different external stimuli and/or fine-tuning the lattice parameters.
Journal ArticleDOI

Hydrogen storage in magnesium-based hydrides and hydride composites

Martin Dornheim, +6 more
- 01 May 2007 - 
TL;DR: In this paper, the authors summarized the recent developments concerning sorption properties and thermodynamics of Mg-based hydrides for hydrogen storage applications in particular, promising strategies to decrease the hydrogen reaction enthalpy by alloying and the use of reactive hydride composites are discussed.
Journal ArticleDOI

Hydrogen sorption properties of MgH2-LiBH4 composites

Ulrike Bösenberg, +11 more
- 01 Jun 2007 - 
TL;DR: A detailed analysis of the reaction mechanism of the reactive hydride composite (RHC) was performed using high-pressure differential scanning calorimetry (HP-DSC) measurements and in situ synchrotron powder X-ray diffraction (XRD) measurements along with kinetic investigations using a Sievert-type apparatus as discussed by the authors.
Journal ArticleDOI

REE Recovery from End-of-Life NdFeB Permanent Magnet Scrap: A Critical Review

Yongxiang Yang, +10 more
- 01 Mar 2017 - 
TL;DR: In this paper, the authors give an overview of the sources of NdFeB permanent magnets related to their applications, followed by a summary of various available technologies to recover the rare-earth elements (REEs) from these magnets, including physical processing and separation, direct alloy production, and metallurgical extraction and recovery.
