    • Anisotropic long-range spin transport in canted antiferromagnetic orthoferrite YFeO3 

      Das, Shubhankar; Ross, A; Ma, X.X.; Becker, S.; Schmitt, C.; van Duijn, Duijn; Galindez-Ruales, E.F.; Fuhrmann, F.; Syskaki, M.-A.; Ebels, U.; Baltz, V.; Barra, A.-L.; Chen, H.Y.; Jakob, G.; Cao, S.X.; Sinova, J.; Gomonay, O.; Lebrun, R.; Klaui, Mathias Michael (Peer reviewed; Journal article, 2022)
      In antiferromagnets, the efficient transport of spin-waves has until now only been observed in the insulating antiferromagnet hematite, where circularly (or a superposition of pairs of linearly) polarized spin-waves diffuse ...

    • Anisotropies and magnetic phase transitions in insulating antiferromagnets determined by a Spin-Hall magnetoresistance probe 

      Lebrun, Romain; Ross, Andrew; Gomonay, Olena; Bender, Scott A.; Baldrati, Lorenzo; Kronast, Florian; Qaiumzadeh, Alireza; Sinova, Jairo; Brataas, Arne; Duine, Rembert; Klaui, Mathias Michael (Journal article; Peer reviewed, 2019)
      Antiferromagnets possess a number of intriguing and promising properties for electronic devices, which include a vanishing net magnetic moment and thus insensitivity to large magnetic fields and characteristic terahertz ...

    • Exploiting Coherence in Nonlinear Spin-Superfluid Transport 

      Tserkovnyak, Yaroslav; Klaui, Mathias Michael (Journal article; Peer reviewed, 2017)
      We show how the interference between superfluid spin currents can endow spin circuits with coherent logic functionality. While the hydrodynamic aspects of the linear-response collective spin transport obviate interference ...

    • Hidden interplay of current-induced spin and orbital torques in bulk Fe3GeTe2 

      Saunderson, Tom G.; Go, Dongwook; Blügel, Stefan; Klaui, Mathias Michael; Mokrousov, Yuriy (Peer reviewed; Journal article, 2022)
      Low crystal symmetry of magnetic van der Waals materials naturally promotes spin-orbital complexity unachievable in common magnetic materials used for spin-orbit torque switching. Here, using first-principles methods, we ...

    • Long-distance spin-transport across the Morin phase transition up to room temperature in ultra-low damping single crystals of the antiferromagnet α-Fe2O3 

      Lebrun, Romain; Ross, Andrew; Gomonay, Olena; Baltz, V.; Ebels, U; Barra, Anne Laure; Qaiumzadeh, Alireza; Brataas, Arne; Sinova, Jairo; Klaui, Mathias Michael (Peer reviewed; Journal article, 2020)
      Antiferromagnetic materials can host spin-waves with polarizations ranging from circular to linear depending on their magnetic anisotropies. Until now, only easy-axis anisotropy antiferromagnets with circularly polarized ...

    • Propagation Length of Antiferromagnetic Magnons Governed by Domain Configurations 

      Ross, Andrew; Lebrun, Romain; Gomonay, Olena; Grave, Daniel A.; Kay, Asaf; Baldrati, Lorenzo; Becker, Sven; Qaiumzadeh, Alireza; Ulloa, Camilo; Jakob, Gerhard; Kronast, Florian; Sinova, Jairo; Duine, Rembert; Brataas, Arne; Rothschild, Avner; Klaui, Mathias Michael (Peer reviewed; Journal article, 2019)
      The compensated magnetic order and characteristic terahertz frequencies of antiferromagnetic materials make them promising candidates to develop a new class of robust, ultrafast spintronic devices. The manipulation of ...

      Klaui, Mathias Michael (Peer reviewed; Journal article, 2022)
      The role of the crystal lattice, temperature and magnetic field for the spin structure formation in the 2D van der Waals magnet Fe5GeTe2 with magnetic ordering up to room temperature is a key open question. Using Lorentz ...
