  • Magnetic aerogels from FePt and CoPt3 directly from organic solution 
    Schoske, L.; Lübkemann-Warwas, F.; Morales, I.; Wesemann, C.; Eckert, J.G.; Graf, R.T.; Bigall, N.C. (Cambridge : RSC Publ., 2024)
    Here the synthesis of magnetic aerogels from iron platinum and cobalt platinum nanoparticles is presented. The use of hydrazine monohydrate as destabilizing agent triggers the gelation directly from organic solution, and ...
  • The mechanically induced structural disorder in barium hexaferrite, BaFe12O19, and its impact on magnetism 
    Sepelak, V.; Myndyk, Maxym; Witte, R.; Roeder, J.; Menzel, Dirk; Schuster, R.H.; Hahn, H.; Heitjans, Paul; Becker, Klaus-Dieter (Cambridge : Royal Society of Chemistry, 2014)
    The response of the structure of the M-type barium hexaferrite (BaFe12O19) to mechanical action through high-energy milling and its impact on the magnetic behaviour of the ferrite are investigated. Due to the ability of ...
  • Observation of correlated spin-orbit order in a strongly anisotropic quantum wire system 
    Brand, C.; Pfnür, Herbert; Landolt, G.; Muff, S.; Dil, J.H.; Das, Tanmoy; Tegenkamp, Christoph (London : Nature Publishing Group, 2015)
    Quantum wires with spin-orbit coupling provide a unique opportunity to simultaneously control the coupling strength and the screened Coulomb interactions where new exotic phases of matter can be explored. Here we report ...
  • On the Severi problem in arbitrary characteristic 
    Christ, Karl; He, Xiang; Tyomkin, Ilya (Berlin ; Heidelberg : Springer, 2022)
    In this paper, we show that Severi varieties parameterizing irreducible reduced planar curves of a given degree and geometric genus are either empty or irreducible in any characteristic. Following Severi’s original idea, ...
  • Origin of metallicity in atomic Ag wires on Si(557) 
    Krieg, U.; Lichtenstein, T.; Brand, C.; Tegenkamp, Christoph; Pfnür, Herbert (Bristol : IOP Publishing Ltd, 2015)
    We investigated the metallicity of Ag-root 3 ordered atomic wires close to one monolayer (ML) coverage, which are formed on Si(557) via self assembly. For this purpose we combined high resolution electron energy loss ...
  • A simple and straightforward mechanochemical synthesis of the far-from-equilibrium zinc aluminate, ZnAl2O4, and its response to thermal treatment 
    Fabian, Martin; Bottke, Patrick; Girman, Vladimir; Duevel, Andre; Da Silva, Klebson Lucenildo; Wilkening, Martin; Hahn, Horst; Heitjans, Paul; Sepelak, Vladimir (Cambridge : Royal Society of Chemistry, 2015-06-08)
    Zinc aluminate (ZnAl2O4) nanoparticles with an average size of about 10 nm are synthesized via one-step mechanochemical processing of the ZnO : γ-Al2O3 stoichiometric mixture at ambient temperature. The mechanochemically ...
