1. Spin transport parameters in metallic multilayers determined by ferromagnetic resonance measurements of spin-pumping
Topic: Condensed Matter Physics
Published: 4/19/2013
Authors: Carl T Boone, Hans Toya Nembach, Justin M Shaw, Thomas J Silva
Abstract: We measured the spin-transport in nonferromagnetic (NM) metallic multilayers from the contribution to damping due to spin pumping from a ferromagnetic Co^d90^Fe^d10^ thin film. The multilayer stack consisted of NM^d1^/NM^d2^/Co^d90^Fe^d10^(2 nm)/NM^d ...

2. Valleytronics, Carrier Filtering and Thermoelectricity in Bismuth: Magnetic Field Polarization Effects
Topic: Condensed Matter Physics
Published: 9/25/2012
Authors: Adrian Popescu, Lilia Woods
Abstract: Valley polarization of multi-valleyed materials is of significant interest for potential applications in electronic devices. The main challenge is removing the valley degeneracy in some controllable way. The unique properties of bismuth in terms of i ...

3. Epitaxial (111) Films of Cu, Ni, and Cu^dx^Ni^dy^ on {alpha}{long dash}Al^d2^O^d3^(0001) for graphene growth by chemical vapor deposition
Topic: Condensed Matter Physics
Published: 9/21/2012
Authors: David Lee Miller, Mark W Keller, Justin M Shaw, Ann Chiaramonti Chiaramonti Debay, Robert R Keller
Abstract: Films of (111)-textured Cu, Ni, and Cu^dx^Ni^dy^ were evaluated as substrates for chemical vapor deposition of graphene. A metal thickness of 400 nm to 700 nm was sputtered onto a substrate of {alpha}{long dash}Al^d2^O^d3^(0001) at temperatures of {I ...

5. Electronic properties of multilayer graphene
Topic: Condensed Matter Physics
Published: 3/31/2012
Author: Hongki Min
Abstract: In this chapter, we study the electronic structure of arbitrarily stacked multilayer graphene in the absence or presence of magnetic field. Energy band structure and Landau level spectrum are obtained using a pi-orbital continuum model with nearest-n ...

Topic: Condensed Matter Physics
Published: 9/15/2011
Authors: Jean-Yves Chauleau, Benjamin James McMorran, R. Belkhou, Nicolas Bergeard, Tevfik Mente?, Miguel Angel Nino, Andrea Locatelli, John Unguris, Stanislas Rohart, Jacques Miltat, Andre Thiaville
Abstract: We have observed peculiar magnetization textures in Ni80Pd20 nanostructures, by three different imaging techniques (MFM, XMCD-PEEM and SEMPA). The appearance of diamond-like domains with strong lateral charges, and of weak stripes structures brings i ...

8. Graphene-metal interconnect: an atomistic simulation
Topic: Condensed Matter Physics
Published: 8/11/2011
Authors: Alexander Y. Smolyanitsky, Vinod K Tewary
Abstract: We develop a set of computationally efficient and accurate interatomic interactions for an atomistic simulation of the properties of graphene on nickel surface. The approach is based on the modified embedded atom method (MEAM) for the C-C and Ni-Ni i ...
