  • Local Magnetic Suppression of Topological Surface States in Bi2Te3 Nanowires
  • 2016

    • Locally induced, magnetic order on the surface of a topological insulator nanowire could enable room-temperature topological quantum devices. Here we report on the realization of selective magnetic control over topological surface states on a single facet of a rectangular Bi2Te3 nanowire via a magnetic insulating Fe3O4 substrate. Low-temperature magnetotransport studies provide evidence for local time-reversal symmetry breaking and for enhanced gapping of the interfacial 1D energy spectrum by perpendicular magnetic-field components, leaving the remaining nanowire facets unaffected. Our results open up great opportunities for development of dissipation-less electronics and spintronics.

  • Magnetic properties of single nanomagnets : Electron energy-loss magnetic chiral dichroism on FePt nanoparticles
  • 2016
  • Ingår i: Ultramicroscopy. - : Elsevier BV. - 0304-3991 .- 1879-2723. ; 171, s. 186-194
  • Tidskriftsartikel (refereegranskat)abstract
    • Electron energy-loss magnetic chiral dichroism (EMCD) allows for the quantification of magnetic properties of materials at the nanometer scale. It is shown that with the support of simulations that help to identify the optimal conditions for a successful experiment and upon implementing measurement routines that effectively reduce the noise floor, EMCD measurements can be pushed towards quantitative magnetic measurements even on individual nanoparticles. With this approach, the ratio of orbital to spin magnetic moments for the Fe atoms in a single Ll(0) ordered FePt nanoparticle is determined to be m(l)/m(s) = 0.08 +/- 0.02. This finding is in good quantitative agreement with the results of XMCD ensemble measurements. (C) 2016 Elsevier B.V. All rights reserved.
