    • Effect of midgap states on the magnetic exchange interaction mediated by a d-wave superconductor 

      Ghanbari Birgani, Atousa; Erlandsen, Eirik; Linder, Jacob (Peer reviewed; Journal article, 2021)
      We theoretically study the indirect interaction between two ferromagnetic contacts located on the surface of a d-wave superconductor. When the magnets are connected to a {010} edge of the superconductor we find an oscillating ...

    • Going beyond the Chandrasekhar-Clogston limit in a flatband superconductor 

      Ghanbari Birgani, Atousa; Erlandsen, Eirik; Sudbø, Asle; Linder, Jacob (Peer reviewed; Journal article, 2022)
      The Chandrasekhar-Clogston limit normally places stringent conditions on the magnitude of the magnetic field that can coexist with spin-singlet superconductivity, restricting the critical induced Zeeman shift to a fraction ...

    • RKKY interaction in a spin-split superconductor 

      Ghanbari Birgani, Atousa; Linder, Jacob (Peer reviewed; Journal article, 2021)
      We determine theoretically the interaction between two magnetic impurities embedded in a spin-split s-wave superconductor. The spin-splitting in the superconductor gives rise to two different interaction types between ...

    • Self-consistent solution for the magnetic exchange interaction mediated by a superconductor 

      Ghanbari Birgani, Atousa; Risinggård, Vetle Kjær; Linder, Jacob (Peer reviewed; Journal article, 2021)
      We theoretically determine the magnetic exchange interaction between two ferromagnets coupled by a superconductor using a tight-binding lattice model. The main purpose of this study is to determine how the self-consistently ...
