    • Backward magnetostatic surface spin waves in coupled Co/FeNi bilayers 

      Song, Wenjie; Wang, Xiansi; Wang, Wenfeng; Jiang, Changjun; Wang, Xiangrong; Chai, Guozhi (Peer reviewed; Journal article, 2020)
      Spin waves (SWs) in coupled Co/FeNi bilayers are probed by the Brillouin light‐scattering technique. Two types of SWs, magnetostatic surface spin waves (MSSWs) and perpendicular standing SWs, are identified. The dispersion ...

    • Current-Driven Dynamics of Magnetic Hopfions 

      Wang, Xiansi; Qaiumzadeh, Alireza; Brataas, Arne (Journal article; Peer reviewed, 2019)
      opological magnetic textures have attracted considerable interest since they exhibit new properties and might be useful in information technology. Magnetic hopfions are three-dimensional (3D) spatial variations in the ...

    • Magnetodynamic properties of dipole-coupled 1D magnonic crystals 

      Singh, Suraj Kumar; Wang, Xiansi; Kumar, Ankit; Qaiumzadeh, Alireza; Svedlindh, Peter; Tybell, Per Thomas Martin; Wahlström, Erik (Journal article, 2021)
      Magnonic crystals are magnetic metamaterials, that provide a promising way to manipulate magnetodynamic properties by controlling the geometry of the patterned structures. Here, we study the magnetodynamic properties of ...

    • Thermal gradient driven domain wall dynamics 

      Torikul, M. T.; Wang, Xiansi; Wang, X. R. (Journal article; Peer reviewed, 2019)
      The issue of whether a thermal gradient acts like a magnetic field or an electric current in the domain wall (DW) dynamics is investigated. Broadly speaking, magnetization control knobs can be classified as energy-driving ...
