Journal ArticleDOI
Premartensitic phenomena in the ferro- and paramagnetic phases of Ni 2 MnGa
TL;DR: In this article, a martensitic phase transformation with a transition temperature of about 80 K below the Curie temperature was studied in the ferromagnetic and paramagnetic phases of the Heusler alloy and the relation of these elastic precursors to the low-temperature structure was discussed.
Journal ArticleDOI
Magnetoelastic excitations in the pyrochlore spin liquid Tb2Ti2O7.
Tom Fennell,Michel Kenzelmann,B. Roessli,Hannu Mutka,Jacques Ollivier,M. Ruminy,Uwe Stuhr,Oksana Zaharko,Laura Bovo,Antonio Cervellino,M. K. Haas,Robert J. Cava +11 more
TL;DR: In this article, the spin liquid phase of Tb2Ti2O7 can be regarded as a Coulomb phase with propagating bosonic spin excitations, and the hybridization of the excitations suppresses both magnetic ordering and the structural distortion.
Journal ArticleDOI
Time-of-flight diffraction with multiple frame overlap Part II: The strain scanner POLDI at PSI
Uwe Stuhr,H. Spitzer,J. Egger,A. Hofer,P. Rasmussen,Dieter Graf,A. Bollhalder,M. Schild,G.S. Bauer,Wolfgang Wagner +9 more
TL;DR: The POLDI (Pulse-OverLap DIffractometer) is a multiple pulse-overlap diffractometer at PSI, which is designed mainly for strain-scanning experiments.
Journal ArticleDOI
Low-frequency vibrational properties of nanocrystalline materials.
TL;DR: It is found that the anomalous increase of the VDOS is mainly caused by the high number of grain-boundary atoms and that a power-law behavior of the low-frequency grain- boundary VDOS exists, which suggests a reduced dimensionality effect.
Journal ArticleDOI
Plasticity of multiscale nanofilamentary Cu/Nb composite wires during in situ neutron diffraction: Codeformation and size effect
Ludovic Thilly,Pierre-Olivier Renault,Vanessa Vidal,Florence Lecouturier,S. Van Petegem,Uwe Stuhr,H. Van Swygenhoven +6 more
TL;DR: In situ neutron diffraction was performed on Cu∕Nb nanocomposite wires composed of a multiscale Cu matrix embedding Nb nanofilaments with a diameter of 267nm and spacing of 45nm as mentioned in this paper.
