Dynamical renormalization of the magnetic excitation spectrum via high-momentum nonlinear magnonics
Christoph Schoenfeld, Lennart Feuerer, Julian Bär +9
Controlling macroscopic properties of quantum materials requires the ability to induce and manipulate excited states. The set of collective excitations of a solid is encoded in its…
Magnetic properties of hematite revealed by an ab initio parameterized spin model
Tobias Dannegger, András Deák, Levente Rózsa +6
Hematite is a canted antiferromagnetic insulator, promising for applications in spintronics. Here, we present ab initio calculations of the tensorial exchange interactions of hemat…
Ultrafast spontaneous spin switching in an antiferromagnet
Marvin A. Weiss, Andreas Herbst, Julius Schlegel +8
Owing to their high magnon frequencies, antiferromagnets are key materials for future high-speed spintronics. Picosecond switching of antiferromagnetic order has been viewed a mile…
