Terahertz switching of antiferromagnetic order by Néel spin-orbit torques

Yannic Behovits, Alexander L. Chekhov, Amon Ruge +13

Ultrafast electric manipulation of magnetic order in solids is critical for the development of future terahertz data processing. A fascinating concept for such high-speed operation…

Quantum fluctuations determine the spin-flop transition in hematite

Tobias Dannegger, Imre Hagymási, Levente Rózsa +1

Magnetic phase transitions between ordered phases are often understood on the basis of semi-classical spin models. Deviations from the classical description due to the quantum natu…

Altermagnetic magnon transport in the \textit{d}-wave altermagnet \ch{LuFeO3}

Edgar Galindez-Ruales, Wanting Yang, Tobias Dannegger +11

Altermagnets exhibit a spin-split band structure despite having zero net magnetization, leading to special magnonic properties such as anisotropic magnon lifetimes and field-free s…

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…

Ultrafast coherent all-optical switching of an antiferromagnet with the inverse Faraday effect

Tobias Dannegger, Marco Berritta, Karel Carva +4

We explore the possibility of ultrafast, coherent all-optical magnetization switching in antiferromagnets by studying the action of the inverse Faraday effect in CrPt, an easy-plan…
