Local Moment Instability of Os in Honeycomb Li 2.15 Os 0.85 O 3 .
Maxwell K. Wallace,P. G. LaBarre,Jun Li,Shu-Ting Pi,Warren E. Pickett,D. S. Dessau,Daniel Haskel,Arthur P. Ramirez,Munirpallam A. Subramanian +8 more
TL;DR: Applied density functional theory (DFT) leads to a reduced moment, suggesting incipient itineracy of the valence electrons, and finding evidence that Li over stoichiometry leads to Os(4+)−Os(5+) mixed valence.
Structure and electronic properties of CaAl12−xFexO19 hibonites
B. A. Duell,Jun Li,P. G. LaBarre,Junjie Zhang,Raphaël P. Hermann,Arthur P. Ramirez,Munirpallam A. Subramanian +6 more
TL;DR: In this paper, the structural effects of larger iron substitution into the aluminum sites and the resultant properties were investigated, and a solid solution exists for CaAl12−xFexO19 where x ≤ 5.5.

Os4+ Instability in the Pyrochlore Structure: Tl2–xBixOs2O7–y
Elizabeth Sobalvarro Converse,Jun Li,Daniel Haskel,P. G. LaBarre,Arthur P. Ramirez,Munirpallam A. Subramanian +5 more
TL;DR: This system gave insight into the bonding preferences of Os, indicating a dependence on high oxidation states and mixed valence for the stability of complex structures.

Evidence for Undoped Weyl Semimetal Charge Transport in $Y_{2}Ir_{2}O_{7}$
TL;DR: Weyl fermions scattering from a random Coulomb potential are predicted to exhibit resistivity versus temperature in a single particle model as discussed by the authors, and the behavior extends into the low-temperature, high resistivity region where the Ioffe-Regel parameter, $k_{T} \ell \ll 2\pi", is the possible origin of such bad Weyl semimetal behavior.

Fluctuation-induced interactions and the spin-glass transition in Fe 2 TiO 5
P. G. LaBarre,D. Phelan,Yan Xin,Feng Ye,Tiglet Besara,Tiglet Besara,Theo Siegrist,Theo Siegrist,Sergey Syzranov,S. Rosenkranz,Arthur P. Ramirez +10 more
TL;DR: In this article, the spin-glass transition in strongly frustrated well-known compound is investigated and a mean-field replica theory of such a transition is developed, revealing a type of magnetic van der Waals effect.
