Christopher L. Holloway, Matthew T. Simons, Abdulaziz H. Haddab, Joshua A. Gordon, David R. Novotny
We demonstrate a Rydberg atom-based sensor embedded in a parallel-plate waveguide (PPWG) for amplitude and phase detection of a radio-frequency (RF) electric field. This embedded atomic sensor is also capable of receiving modulated communications signals

Spin Seebeck Imaging of Spin-Torque Switching in Antiferromagnetic Pt/NiO Heterostructures

Isaiah Gray, Takahiro Moriyama, Nikhil Sivadas, Gregory M. Stiehl, John T. Heron, Ryan F. Need, Brian Kirby, David H. Low, Katja Nowack, Darrell G. Schlom, Daniel C. Ralph, Teruo Ono, Gregory D. Fuchs
We demonstrate the spin Seebeck microscope as a sensitive method for imaging in-plane antiferromagnetic order in thin films. Recently, antidamping spin-orbit torques have been used to reorient Neel order in antiferromagnetic devices. Although the readout

Vapor deposition of a nonmesogen prepares highly structured organic glasses

October 22, 2019
Author(s)
Camille Bishop, Jacob L. Thelen, Eliot Gann, Michael F. Toney, Lian Yu, Dean DeLongchamp, Mark D. Ediger
We show that glasses with aligned smectic liquid crystal-like order can be produced by physical vapor deposition of a molecule without any equilibrium liquid crystal phases. Smectic-like order in vapor-deposited films was characterized by wide-angle X-ray
