• Electrically driven Bose-Einstein condensation of magnons in antiferromagnets 

      Fjærbu, Eirik Løhaugen; Rohling, Niklas; Brataas, Arne (Journal article; Peer reviewed, 2017)
      We explore routes to realize electrically driven Bose-Einstein condensation of magnons in insulating antiferromagnets. Even in insulating antiferromagnets, the localized spins can strongly couple to itinerant spins in ...
    • Magnetization Dissipation in Bulk Ferromagnets and Ferromagnetic Quantum Dots 

      Fjærbu, Eirik Løhaugen (Master thesis, 2014)
      We study the magnetization dynamics of a nano-scale ferromagnet. We show that the phenomenological Landau-Lifschitz-Gilbert predicts a damped precession of the magnetization. The ferromagnet is coupled to two large reservoirs ...
    • Quantum Phenomena at Magnetic Insulator-Normal Metal Interfaces 

      Fjærbu, Eirik Løhaugen (Doctoral theses at NTNU;2018:249, Doctoral thesis, 2018)
      Electrons carry an intrinsic angular momentum that we call spin. Spintronics is a field of research which aims to create new computer technology by making use of the electron spin. This thesis presents the results of four ...
    • Superconductivity induced by interfacial coupling to magnons 

      Rohling, Niklas; Fjærbu, Eirik Løhaugen; Brataas, Arne (Journal article; Peer reviewed, 2018)
      We consider a thin normal metal sandwiched between two ferromagnetic insulators. At the interfaces, the exchange coupling causes electrons within the metal to interact with magnons in the insulators. This electron-magnon ...
