Three-Dimensional Neutron Far-Field Tomography of a Bulk Skyrmion Lattice

August 13, 2023
Author(s)
Melissa Henderson, Benjamin Heacock, Markus Bleuel, David Cory, Colin Heikes, Michael G. Huber, Jeffery Krzywon, Olivier Nahman-Levesque, Graeme Luke, M Pula, Dusan Sarenac, Kirill Zhernenkov, Dmitry Pushin
Magnetic skyrmions are localized non-collinear spin textures, characterized by an integer topo-logical charge. Their nanometric size and topological protection gives rise to unique dynamics and emergent electromagnetic phenomena, ideal for spintronic

Deformation of the Moving Magnetic Skyrmion Lattice in MnSi under Electric Current Flow

July 11, 2019
Author(s)
D. Okuyama, Markus Bleuel, J. S. White, Qiang Ye, Jeffery R Krzywon, G. Nagy, Z. Q. Im, I. Zivkovic, M. Bartkowiak, H. M. Ronnow, S. Hoshino, J. Iwasaki, N. Nagaosa, A. Kikkawa, Y. Taguchi, Y. Tokura, D. Higashi, J. D. Reim, Y. Nambu, T. J. Sato
Topological defects are found ubiquitously in various kinds of matter, such as vortices in type-II superconductors, and magnetic skyrmions in chiral ferromagnets. While knowledge on the static behavior of magnetic skyrmions is accumulating steadily, their

Learning About SANS Instruments and Data Reduction from Round Robin Measurements on Samples of Polystyrene Latex

October 1, 2013
Author(s)
Adrian R. Rennie, Maja S. Hellsing, Kathleen Wood, Elliot P. Gilbert, Lionel Porcar, Ralf Schweins, Charles D. Dewhurst, Peter Lindner, Richard K. Heenan, Sarah E. Rogers, Paul Butler, Jeffery R Krzywon, Ron E. Ghosh, Andrew J. Jackson, Marc Malfois
Round-robin measurements of polystyrene latex samples at a number of small-angle scattering facilities have been used to assess the current limits of reliability and reproducibility of scattering data as well as the accuracy of parameters derived from
