Multiferroic FeTe 2 O 5 Br: Alternating spin chains with frustrated interchain interactions
Matej Pregelj,Harald Olaf Jeschke,H. Feldner,Roser Valentí,Andreas Honecker,Tanusri Saha-Dasgupta,Hena Das,Shunsuke Yoshii,Takayuki Morioka,Hiroyuki Nojiri,Helmuth Berger,Andrej Zorko,Oksana Zaharko,Denis Arčon,Denis Arčon +14 more
TL;DR: In this article, a combination of density functional theory calculations, many-body model considerations, and magnetization and electron-spin-resonance measurements is used to show that the multiferroic FeTe2O5Br should be described as a system of alternating antiferromagnetic S = 5/2 chains with strong Fe-O-Te O-Fe bridges weakly coupled by two-dimensional frustrated interactions, rather than the previously reported tetramer model.
Effect of hydrogen on degradation mechanism of zirconium: A molecular dynamics study
TL;DR: In this paper, the effect of hydrogen atoms in dilute and concentrated limit of Zr was investigated using large-scale molecular dynamics simulation, and the deformation behavior was characterized using stress-strain curves and micro-structure analysis at different strain values.

Relative stability of zincblende and wurtzite structure in CdX(X = S, Se, Te) series - A NMTO study
TL;DR: Using NMTO-downfolding technique, the authors revisited the issue of relative stability between zincblende (ZB) and wurtzite (WZ) symmetries in case of CdS, CdSe and CdTe semiconductors.

Electronic Structure of Oxide Interfaces: A Comparative Analysis of GdTiO3/SrTiO3 and LaAlO3/SrTiO3 Interfaces.
TL;DR: Ab-initio electronic structure calculations for the interface between a Mott insulator GdTiO3 (GTO) and a band insulator SrTiO 3 (STO) are presented and the results are in excellent agreement with experiments, but qualitatively different from LAO/STO.
Competition between heavy fermion and Kondo interaction in isoelectronic A-site-ordered perovskites

TL;DR: X-ray spectroscopy and electronic structure calculations on A-site-ordered perovskites with Cu in the A- site and the B-sites descending along the ninth group of the periodic table are performed to elucidate the emerging properties as d-orbitals change from partially filled 3d to 4d to 5d.
