Researchers from Eindhoven University of Technology Report on Findings in Science (Tunable chiral spin texture in magnetic domain-walls)

August 29, 2014

By a News Reporter-Staff News Editor at Science Letter -- Research findings on Science are discussed in a new report. According to news reporting from Eindhoven, Netherlands, by NewsRx journalists, research stated, "Magnetic domain-walls (DWs) with a preferred chirality exhibit very efficient current-driven motion. Since structural inversion asymmetry (SIA) is required for their stability, the observation of chiral domain walls in highly symmetric Pt/Co/Pt is intriguing."

The news correspondents obtained a quote from the research from the Eindhoven University of Technology, "Here, we tune the layer asymmetry in this system and observe, by current-assisted DW depinning experiments, a small chiral field which sensitively changes. Moreover, we convincingly link the observed efficiency of DW motion to the DW texture, using DW resistance as a direct probe for the internal orientation of the DW under the influence of in-plane fields."

According to the news reporters, the research concluded: "The very delicate effect of capping layer thickness on the chiral field allows for its accurate control, which is important in designing novel materials for optimal spin-orbit-torque-driven DW motion."
