 2017-02-2809:32 [FZJ-2017-01958] Journal Article et al Magnetism in a graphene- 4 f − 3 d hybrid system We create an interface of graphene with a metallic and magnetic support that leaves its electronic structure largely intact. This is achieved by exposing epitaxial graphene on ferromagnetic thin films of Co and Ni to vapor of the rare earth metal Eu at elevated temperatures, resulting in the intercalation of an Eu monolayer in between graphene and its substrate.

Using the Rashba model, the tensor of exchange interactions is extracted wherein a thepseudo-dipolar interaction is found, in addition to the usual isotropic exchange interaction and the Dzyaloshinskii–Moriya interaction.

This paper introduces a new satellite record of gravity wave activity in the polar lower stratosphere to investigate this process.

Constitutive activation of STAT5 is a hallmark of myeloid and lymphoblastic leukemia. [...] OpenAccess: PDF PDF (PDFA); 2017-02-2311:56 [FZJ-2017-01934] Book/Report Lieck, B. Extrazelluläre Ableitung elektrisch erregbarer Zellen [Juel-4324] Berichte des Forschungszentrums Jülich 4324, III, 42 p. (2010) In dieser Arbeit wurden zwei Messsysteme zur extrazellulären Ableitung von Zellsignalen vorgestellt und die damit durchgeführten Experimente erläutert. Dabei wurden verschiedene MEAs mit unterschiedlichen Elektrodengrößen und Beschichtungen verwendet.Die „Standard“ Gold MEAs werden immer weiter modifiziert, um die Elektroden möglichst klein zu halten, dafür aber immer größere Elektrodenoberflächen zu schaffen.

(2013) The present document is the proceedings of the 2nd Annual Workshop of the Euratom FP7 Collaborative Project SKIN (Slow processes in close-to-equilibrium conditions for radionuclides in water/solid systems of relevance to nuclear waste management). The project started in Januaray 2011 and has three years duration.

By acting as cloud condensation nuclei (CCN), SOA influences cloud formation and climate. [...] OpenAccess: PDF PDF (PDFA); 2017-02-2010:36 [FZJ-2017-01884] Journal Article et al Contact-Free Mapping of Electronic Transport Phenomena of Polar Domains in SrMnO$_{3}$ Films Physical review applied 5(5), 054009 (2016) [10.1103/PhysRevApplied.5.054009]   High-resolution mapping of electronic transport phenomena plays an increasingly important role for the characterization of ferroic domains and their functionality. At present, spatially resolved electronic transport data are commonly gained from local two-point measurements, collected in line-by-line scans with a conducting nanosized probe. [...] OpenAccess: PDF PDF (PDFA); 2017-02-2010:35 [FZJ-2017-01883] Journal Article et al Energetic, spatial, and momentum character of the electronic structure at a buried interface: The two-dimensional electron gas between two metal oxides   The interfaces between two condensed phases often exhibit emergent physical properties that can lead to new physics and novel device applications and are the subject of intense study in many disciplines. We here apply experimental and theoretical techniques to the characterization of one such interesting interface system: the two-dimensional electron gas (2DEG) formed in multilayers consisting of SrTiO3 (STO) and GdTiO3 (GTO).

The spectroscopy data are interpreted in terms of the existence of heavy 4f surface states, which may be useful in resolving the controversy concerning the disparate surface Fermi-surface velocities observed in experiments.
