Journal ArticleDOI
Low-temperature ferromagnetism in (Ga, Mn)N: Ab initio calculations
TL;DR: The magnetic properties of dilute magnetic semiconductors (DMSs) are calculated from first-principles by mapping the ab initio results on a classical Heisenberg model as discussed by the authors.
Journal ArticleDOI
Einstein oscillators in thallium filled antimony skutterudites.
Raphaël P. Hermann,Rongying Jin,Werner Schweika,Fernande Grandjean,David Mandrus,Brian C. Sales,Gary J. Long +6 more
TL;DR: Heat capacity measurements on Tl0.8Co4Sb11Sn as compared to CoSb3 are consistent with the presence of a localized vibrational mode associated with the "rattling" thallium atoms in this filled skutterudite compound, providing perhaps the clearest example of local mode behavior in a concentrated metallic system.
Journal ArticleDOI
Dumbbell rattling in thermoelectric zinc antimony
TL;DR: This study suggests that soft localized phonon modes in crystalline solids are not restricted to cagelike structures and are likely to be a universal feature of good thermoelectric materials.
Journal ArticleDOI

TL;DR: The European Spallation Source (ESS) as mentioned in this paper consists of a high-power accelerator and target station, providing a unique long-pulse time structure of slow neutrons.
Journal ArticleDOI
Investigation of the hydrogen mobility in a mixed perovskite: Ba[Ca(1+x)/3Nb(2−x)/3]O3−x/2 by quasielastic neutron scattering
