    • Large surface magnetization in noncentrosymmetric antiferromagnets 

      Lund, Mike Alexander; Everschor-Sitte, Karin; Hals, Kjetil Magne Dørheim (Peer reviewed; Journal article, 2020)
      Thin-film antiferromagnets (AFs) with Rashba spin-orbit coupling are theoretically investigated. We demonstrate that the relativistic Dzyaloshinskii-Moriya interaction (DMI) produces a large surface magnetization and a ...

    • Spin Dynamics in Antiferromagnetic Systems 

      Lund, Mike Alexander (Doctoral dissertations at University of Agder;no. 521, Doctoral thesis, 2025)
      This dissertation presents three research papers on spintronics-related effects. Two of the papers discuss dynamic spin phenomena in noncollinear antiferromagnets (NCAFMs). The third paper investigates the equilibrium ...

    • Spin pumping in noncollinear antiferromagnets 

      Lund, Mike Alexander; Salimath, Akshaykumar; Hals, Kjetil Magne Dørheim (Peer reviewed; Journal article, 2021)
      The ac spin pumping of noncollinear antiferromagnets is theoretically investigated. Starting from an effective action description of the spin system, we derive the Onsager coefficients connecting the spin pumping and ...

    • Voltage-Controlled High-Bandwidth Terahertz Oscillators Based on Antiferromagnets 

      Lund, Mike Alexander; Rodrigues, Davi R.; Everschor-Sitte, Karin; Hals, Kjetil Magne Dørheim (Peer reviewed; Journal article, 2023)
      Producing compact voltage-controlled frequency generators and sensors operating in the terahertz (THz) regime represents a major technological challenge. Here, we show that noncollinear antiferromagnets (NCAFM) with kagome ...
