• Andreev reflection in altermagnets 

      Sun, Chi; Brataas, Arne; Linder, Jacob Wüsthoff (Journal article; Peer reviewed, 2023)
      Recent works have predicted materials featuring bands with a large spin-splitting distinct from ferromagnetic and relativistically spin-orbit-coupled systems. Materials displaying this property are known as altermagnets ...
    • Spin pumping from a ferromagnetic insulator into an altermagnet 

      Sun, Chi; Linder, Jacob Wüsthoff (Journal article; Peer reviewed, 2023)
      A class of antiferromagnets with spin-polarized electron bands, yet zero net magnetization, called altermagnets, is attracting increasing attention due to their potential use in spintronics. Here, we study spin injection ...
    • Spin pumping from a ferromagnetic insulator to an unconventional superconductor with interfacial Andreev bound states 

      Sun, Chi; Linder, Jacob Wüsthoff (Journal article; Peer reviewed, 2023)
      Spin pumping from a ferromagnetic insulator into a high-Tc superconductor with a d-wave superconducting order parameter has recently been experimentally observed. Such unconventional superconducting order is known to ...
    • Stability of superconducting gap symmetries arising from antiferromagnetic magnons 

      Sun, Chi; Mæland, Kristian; Sudbø, Asle (Peer reviewed; Journal article, 2023)
      We consider a planar heterostructure consisting of a normal metal in proximity to an antiferromagnetic insulator, with an interlayer exchange coupling between the metal and the insulator. The coupling to the two sublattices ...
