Antiferromagnetism in NdBa2Cu3O6.1
A. H. Moudden,Gen Shirane,John M. Tranquada,Robert J. Birgeneau,Yasuo Endoh,Kazuyoshi Yamada,Yoshikazu Hidaka,Toshiaki Murakami +7 more
TL;DR: The average staggered magnetization evaluated at room temperature is about 0.40μ B in the CuO 2 planes and about 1.04μB in the oxygen-deficient layers.

Widespread nematic fluctuations in the (Sr,Na)Fe$_2$As$_2$ family of superconductors
Benjamin A. Frandsen,Keith M. Taddei,Daniel E. Bugaris,Ryan Stadel,Ming Yi,Arani Acharya,Raymond Osborn,Stephan Rosenkranz,Omar Chmaissem,Robert J. Birgeneau +9 more
TL;DR: In this paper, the authors report comprehensive pair distribution function measurements of the hole-doped iron-based superconductor system and reveal orthorhombic distortions of the instantaneous local structure across a large region of the phase diagram possessing average tetragonal symmetry.
Book ChapterDOI
Fluctuations in One-Dimensional Magnets: Low Temperatures and Long Wavelengths
TL;DR: The one-dimensional properties of the linear-chain antiferromagnet (CH3)4NMnCl3 (TMMC) were first demonstrated by Dingle et al. as mentioned in this paper.
Journal ArticleDOI
Electronic Structure of PrFeAsO1−δ : An Investigation Using X-ray Absorption and Emission Spectroscopy
Byron Freelon,Yuhao Liu,Yi-Sheng Liu,Costel R. Rotundu,Stephen D. Wilson,J.-H. Guo,Jeng-Lung Chen,Jeng-Lung Chen,Wanli Yang,C. L. Chang,Per-Anders Glans,Parasharam M. Shirage,Akira Iyo,Robert J. Birgeneau,Robert J. Birgeneau +14 more
TL;DR: In this paper, soft X-ray absorption and emission spectroscopy was used to determine the electronic density of states of oxygen vacated PrFeAsO. The measured oxygen and iron spectra are in good agreement with mean field theory and local density approximations.
Journal ArticleDOI
The influence of magnetic order on the magnetoresistance anisotropy of Fe$_{1+\delta-x}$Cu$_{x}$Te
TL;DR: It is suggested that under an external magnetic field the resistance anisotropy mirrors the magnetic order parameter, and similarities to nematic order observed in other iron pnictide materials are discussed.
