Journal ArticleDOI
Magnetoelastic excitation spectrum in the rare-earth pyrochlore Tb 2 Ti 2 O 7
M. Ruminy,Solène Guitteny,J. Robert,L. P. Regnault,Martin Boehm,Paul Steffens,Hannu Mutka,Jacques Ollivier,Uwe Stuhr,Jonathan S. White,B. Roessli,Laura Bovo,C. Decorse,M. K. Haas,R. J. Cava,I. Mirebeau,Michel Kenzelmann,S. Petit,Tom Fennell +18 more
TL;DR: In this paper, a detailed characterization of the magnetic and phononic branches of the magnetoelastic mode was presented, particularly with respect to their composition, the anisotropy of any magnetic fluctuations, and also the temperature dependence of the different types of fluctuation that are involved.
Journal ArticleDOI
Relaxation of dynamically disordered tetragonal platelets in the relaxor ferroelectric 0.964 Na 1 / 2 Bi 1 / 2 TiO 3 − 0.036 BaTiO 3
Florian Pforr,Kai-Christian Meyer,Marton Major,Karsten Albe,Wolfgang Donner,Uwe Stuhr,Alexandre Ivanov +6 more
TL;DR: In this paper, Pforr et al. showed that the relaxational dynamics of NBT-3.6BT are concentrated in the tetragonal platelets, whose relaxation back into a quasistable state might explain the frequency dependence of the dielectric properties.
Journal ArticleDOI
A neutron diffraction study of the interstitial sites of deuterium in the A-15 compound Ti3Ir
TL;DR: In this article, the interstitial D sites in the D-doped A-15 compound Ti3IrDx with x = 0.70 and 3.63 were determined by neutron diffraction (space group Pm 3 n (No. 223)).
Journal ArticleDOI
Influence of tetragonal platelets on the dielectric permittivity of 0.964 Na 1 /2 Bi 1 /2 TiO 3 -0.036 BaTiO 3
TL;DR: In this paper, the temperature-dependent evolution of the octahedral tilt order in a lead-free relaxor ferroelectric and its impact on the dielectric properties were studied.
Journal ArticleDOI
Effects of Quantum Spin-1/2 Impurities on the Magnetic Properties of Zigzag Spin Chains.
Koushik Karmakar,M. Skoulatos,M. Skoulatos,Giacomo Prando,Giacomo Prando,Bertran Roessli,Uwe Stuhr,F. Hammerath,Christian Rüegg,Christian Rüegg,Surjeet Singh +10 more
TL;DR: It is found that dilute Co doping induces an Ising-like anisotropy and enhances the magnetic ordering temperature rather significantly, but preserves the gapless nature of the spin excitations.
