Neutron diffraction measurements were carried out on single crystals and powders of Yb 2Pt 2Pb, where Yb moments form planes of orthogonal dimers in the...

Controllable Positive Exchange Bias via Redox-Driven Oxygen Migration

Author(s)
Dustin A. Gilbert, Justin Olamit, Randy K. Dumas, Brian J. Kirby, Alexander J. Grutter, Brian B. Maranville, Elke Arenholz, Julie A. Borchers, Kai Liu
We have observed oxygen migration across buried interfaces in Gd^xdx^Fe 1-x/NiCoO films, which leads to tunable positive exchange bias over a relatively small...

Thermodynamic equilibrium calculations, as well as perfectly-stirred reactor (PSR) simulations with detailed reaction kinetics, are performed for a potential...

Behavior of molecules and molecular ions near a field emitter

Author(s)
Ann C. Chiaramonti Debay, Baptiste Gault, Michael Ashton, Susan B. Sinnott, Michael P. Moody, David W. Saxey, D. K. Schreiber
The cold emission of particles from surfaces under intense electric fields is a process which underpins a variety of applications including atom probe...

Hotspot Relaxation Dynamics in a Current Carrying Superconductor

Author(s)
Francesco Marsili, Martin Stevens, Alex Kozorezov, Varun Verma, Colin Lambert, Jeffrey A. Stern, Rob Horansky, Shellee D. Dyer, Shannon Duff, David P. Pappas, Matthew Shaw, Richard Mirin, Sae Woo Nam
When a photon is absorbed in a superconductor it creates a region of nonequilibrium superconductivity referred to as a hotspot [1]. The operation of most...

Anomalous broadening in driven dissipative Rydberg systems

Author(s)
Elizabeth A. Goldschmidt, Thomas L. Boulier, Roger C. Brown, Silvio B. Koller, Jeremy T. Young, Alexey V. Gorshkov, S L. Rolston, James V. Porto
We observe interaction-induced broadening of the two-photon 5s-18s transition in 87Rb atoms trapped in a 3D optical lattice. The measured linewidth increases by...

Stochastic behavior of nanoscale dielectric wall buckling

Author(s)
Lawrence H. Friedman, Igor Levin, Robert F. Cook
