Abstract

Viewpoint Magnetism Nanophysics Physics 1, 17 (2008) doi:10.1103/Physics.1.17 Flipping a domain wall switch By Mathias Kläui Fachbereich Physik & Zukunftskolleg, Universität Konstanz, 78457 Konstanz, GermanyPublished September 2, 2008 Most applications based on magnetism are incompatible with domain walls, which interrupt a homogeneous magnetization. Scientists are turning this view around as they discover new ways to use an electric current to manipulate and store information in nanoscale domain walls.
