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 ... -
Magnon-Mediated Indirect Exciton Condensation through Antiferromagnetic Insulators
Johansen, Øyvind; Kamra, Akashdeep; Ulloa, Camilo; Brataas, Arne; Duine, Rembert (Journal article; Peer reviewed, 2019)Electrons and holes residing on the opposing sides of an insulating barrier and experiencing an attractive Coulomb interaction can spontaneously form a coherent state known as an indirect exciton condensate. We study a ... -
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 ... -
Spin current cross-correlations as a probe of magnon coherence
Bender, Scott A.; Kamra, Akashdeep; Belzig, Wolfgang; Duine, Rembert (Peer reviewed; Journal article, 2019)Motivated by the important role of the normalized second-order coherence function, often called g(2), in the field of quantum optics, we propose a method to determine magnon coherence in solid-state devices. Namely, we ...
