    The textures of chondritic meteorites demonstrate that they are not the products of planetary melting processes. This has long been interpreted as evidence that chondrite parent bodies never experienced large-scale melting. ...

    Part of Focus on Diamond-Based Photonics and Spintronics We demonstrate a method of imaging spatially varying magnetic fields using a thin layer of nitrogen-vacancy (NV) centers at the surface of a diamond chip. ...
  • Ribeiro, P.; Lee, Patrick A. (American Physical Society, 2011-06)
    We address the problem of a magnetic impurity in a two-dimensional U(1) spin liquid where the spinons have gapless excitations near the Fermi surface and are coupled to an emergent gapless gauge field. Using a large N ...
  • Urdaniz, M. C.; Barral, M. A.; Llois, A. M.; Saul, Alberto Andres (American Physical Society, 2014-11)
    In this work we present a systematic study of the magnetic interactions within 3d transition-metal chains adsorbed on Cu[subscript 2]N and Cu[subscript 2]O monolayers grown on Cu(001). We are interested in the particular ...
  • Lee, Joo-Hyoung; Grossman, Jeffrey C. (American Institute of Physics (AIP), 2010-09)
    The magnetic properties of graphene-graphane superlattices with zigzag interfaces and separately varying widths are investigated by first-principles density functional calculations. It is demonstrated that magnetic states ...
  • Newman, Bonna Kay; Brahms, Nathan; Au, Yat Shan; Johnson, Cort; Connolly, Colin B.; Doyle, John M.; Kleppner, Daniel; Greytak, Thomas J. (American Physical Society, 2011-01)
    The collisional magnetic reorientation rate constant gR is measured for magnetically trapped atomic dysprosium (Dy), an atom with large magnetic dipole moments. Using buffer gas cooling with cold helium, large numbers ...
  • Lee, J. H.; Holmes, S. N.; Hong, B.; Roy, P. E.; Mascaro, M. D.; Hayward, T. J.; Anderson, D.; Cooper, K.; Jones, G. A. C.; Vickers, M. E.; Barnes, C. H. W.; Ross, Caroline A. (American Institute of Physics (AIP), 2009-10)
    The magnetic remanent states and switching behavior of Fe thin-film split-rings are investigated using magnetic force microscopy, magnetoresistance measurements, and micromagnetic simulations in order to assess their ...
  • Cannon, Benjamin Louis; Hoburg, James F.; Stancil, Daniel D.; Goldstein, Seth Copen (Institute of Electrical and Electronics Engineers, 2009-07)
    Wireless power transfer via magnetic resonant coupling is experimentally demonstrated in a system with a large source coil and either one or two small receivers. Resonance between source and load coils is achieved with ...
  • Cantillon-Murphy, Padraig; Ryou, Marvin; Shaikh, Sohail N.; Azagury, Dan; Ryan, Michele; Thompson, Christopher C.; Lang, Jeffrey H. (Institute of Electrical and Electronics Engineers, 2010-08)
    Clinical endoscopic intervention of the pancreaticobiliary tree [endoscopic retrograde cholangiopancreatography (ERCP)] often concludes with the insertion of a temporary plastic stent to reduce the risk of post-ERCP ...
  • DeLauter, Jonathan; DeKamp, Jon C.; Zeller, Al F.; Gung, Chen-yu; Minervini, Joseph V. (Institute of Electrical and Electronics Engineers, 2009-06)
    A small dipole magnet designed for use in high-radiation environments that uses metal-oxide cable-in-conduit-conductor has been constructed and tested for magnetic properties. The conductor consisted of 42 strands of 0.5 ...
  • Miao, Guo-Xing; Moodera, Jagadeesh (American Physical Society, 2012-04)
    The chalcogenide compound EuO is best known as a highly efficient spin-filter tunnel barrier material. Using the molecular beam epitaxy method, we combine polycrystalline EuO with epitaxial MgO and construct magnetic tunnel ...
  • Ko, Wing Ho; Lee, Patrick A. (American Physical Society, 2011-04)
    Motivated by the debate of the spin-density-wave (SDW) versus local-moment (LM) picture in the iron-based superconducting (FeSC) materials, we consider a two-band orbital-symmetric Hubbard model in which there is robust ...
