The Magnetic Transitions and Dynamics in the Multiferroic Lu 0.5 Sc 0.5 FeO 3

February 26, 2016
Author(s)
Junjie Yang, Chunruo Duan, John R. Copley, Craig Brown, Despina Louca
In spite of its frustrated lattice, the multiferroic Lu 0.5Sc 0.5FeO 3 exhibits two consecutive magnetic transitions at T% N1approximately equal to}175 K and T N2 approximately equal to}70 K determined from neutron diffraction. In the ordered state

Manipulating Three-Dimensional Gel Network Entanglement by Thin Film Shearing

February 25, 2016
Author(s)
Harshita Kumari, Steven R. Kline, Stuart R. Kennedy, Christopher Garvey, Colin L. Raston, Jerry L. Atwood, Jonathan W. Steed
Vortex fluidic mediated shearing of supramolecular gels in thin films leads to complete disruption of fluorous bis-urea derived gels. Hydrocarbon analogues however, are only partially disrupted, which emphasizes the resistance of nonfluorous bis-urea

Optimization of Registration Performance Metrics

February 25, 2016
Author(s)
Marek Franaszek, Geraldine Cheok
Perception systems are a very important component of automation and robotics. These systems localize objects in its local coordinate frame and the data has to be available for use in another coordinate frame. This requires that the data be transformed from

The Structural Origin of Electron Injection Enhancements with Fulleropyrrolidine Interlayers

February 25, 2016
Author(s)
Lee J. Richter, Hyunbok Lee, Christopher McNeil, Eliot Gann, Lars Thomsen, S. Park, J. Jeong, Z. A. Page, Egle Puodziukynaite, Todd Emrick, Alejandro Briseno, John C. Stephenson, Dean M. DeLongchamp
Market demand for ubiquitous, increased functionality products at low cost (the internet of things) is spurring development in additive, solution processing of electronic devices. Performance in thin-film functional devices, be they transistors, diodes, or

Through-the-Glass Spectroscopic Ellipsometry for Analysis of CdTe Thin-Film Solar Cells in the Superstrate Configuration

February 25, 2016
Author(s)
Prakash Koirala, Jian Li, Heayoung Yoon, Puruswottam Aryal, Sylvain Marsillac, Angus R. Rockett, Nikolas Podraza, Robert W. Collins
Polycrystalline CdS/CdTe thin-film solar cells in the superstrate configuration have been studied by spectroscopic ellipsometry (SE) using glass side illumination. In this measurement method, the first reflection from the ambient/glass interface is

Validation and Verification of Collisional-Radiative Models

February 25, 2016
Author(s)
Yuri Ralchenko
Quality control is as relevant to scientific computing as to any other software. For complex collisional-radiative (CR) models that are used to calculate plasma population kinetic parameters and spectra, each computer code is expected to be thoroughly

Reversible Control of Magnetism in La 0.67 Sr 0.33 MnO 3 through Chemically-Induced Oxygen Migration

February 24, 2016
Author(s)
Alexander J. Grutter, Dustin A. Gilbert, U. S. Alaan, E. Arenholz, Brian B. Maranville, Julie A. Borchers, Y. Suzuki, Kai Liu, Brian J. Kirby
We demonstrate reversible control of magnetization and anisotropy in La 0.67Sr 0.33MnO 3 films through interfacial oxygen migration. Gd metal capping layers deposited onto La 0.67Sr 0.33MnO 3 leach Oxygen from the film through a solid-state redox reaction

Spintronics: Chiral damping

February 24, 2016
Author(s)
Kyoung-Whan Kim, Hyun-Woo Lee
Many objects in nature prefer to spiral in one particular direction to the other. A nanostructured magnetic system with strong spin-orbit coupling now shows that the energy loss is also chiral.

Uranium Ion Yields from Monodisperse Uranium Oxide Particles

February 24, 2016
Author(s)
Nicholas E. Sharp, John D. Fassett, David S. Simons
Secondary ion mass spectrometry (SIMS) plays an important role in nuclear forensics through its ability to identify isotopic ratios of particles accurately and precisely from samples obtained by inspectors [1]. As the particle mass can be on the order of

Current Standards Landscape for Smart Manufacturing Systems

February 23, 2016
Author(s)
Yan Lu, Katherine C. Morris, Simon P. Frechette
The future of manufacturing lies in being able to optimize the use of resources to produce high quality product and adapt quickly to changing conditions. From smaller lot sizes, to more customization, to sudden changes in supply chain; the variability that
