We have carried out neutron spectroscopic measurements on single crystals of La_{1.6−x}Nd_{0.4}Sr_{x}CuO_{4} from 0.12≤x≤0.26 using time-of-flight techniques. These measurements allow us to follow the evolution of parallel spin stripe fluctuati

Topologically nontrivial spin textures host great promise for future spintronic applications. Skyrmions in particular are of burgeoning interest owing to their nanometric size, topological protection, and high mobility via ultra-low current densities

Parallel spin stripes and their coexistence with superconducting ground states at optimal and high doping in La_{1.6−x}Nd_{0.4}Sr_{x}CuO_{4}
Autor: Qianli Ma, Kirrily C. Rule, Zachary W. Cronkwright, Mirela Dragomir, Gabrielle Mitchell, Evan M. Smith, Songxue Chi, Alexander I. Kolesnikov, Matthew B. Stone, Bruce D. Gaulin

Three-dimensional, commensurate long-range magnetic order in La_{2}CuO_{4} quickly evolves to quasi-two-dimensional, incommensurate correlations upon doping with mobile holes, and superconductivity follows for x as small as 0.05 in the La_{2−x}Sr_{

Boron is a quintessential crustal element but its conspicuous presence in diamond – a mantle mineral – raises questions about potential subduction pathways for boron and other volatiles. It has been a long-standing goal to characterize the isotop

The new mineral crowningshieldite: A high-temperature NiS polymorph found in a type IIa diamond from the Letseng mine, Lesotho
Autor: L. Secco, Fabrizio Nestola, Evan M. Smith, Leonardo Pasqualetto, Wuyi Wang, Federico Zorzi
Publikováno v: American Mineralogist. 106:301-308
Crowningshieldite is the natural analog of the synthetic compound α-NiS. It has a NiAs-type structure and is the high-temperature polymorph relative to millerite (β-NiS), with an inversion temperature of 379 °C. Crowningshieldite is hexagonal, spa

Tunable indium tin oxide for metamaterial perfect absorbers and nonlinear devices
Autor: Kevin D. Leedy, Junpeng Guo, Evan M. Smith, Joshua R. Hendrickson, Shivashankar Vangala, Justin W. Cleary
Publikováno v: MRS Communications. 10:573-578
Indium tin oxide (ITO) has become a very useful plasmonic and nonlinear optical material because of its highly tunable electrical and optical properties and strong optical nonlinearity. In this work, the authors conducted detailed fabrication process
