Defect-enhanced diffusion of magnetic skyrmions
Philipp Rieger, Markus Weißenhofer, Ulrich Nowak
Defects, i.e. inhomogeneities of the underlying lattice, are ubiquitous in magnetic materials and can have a crucial impact on their applicability in spintronic devices. For magnet…
Magnon squeezing in conical spin spirals
Dennis Wuhrer, Levente Rózsa, Ulrich Nowak +1
We investigate squeezing of magnons in a conical spin spiral configuration. We find that while the energy of magnons propagating along the and the $-\boldsymbol{k}…
Calculating spin-lattice interactions in ferro- and antiferromagnets: the role of symmetry, dimension and frustration
Hannah Lange, Sergiy Mankovsky, Svitlana Polesya +3
Recently, the interplay between spin and lattice degrees of freedom has gained a lot of attention due to its importance for various fundamental phenomena as well as for spintronic…
Néel-Vector Switching and THz Spin-Wave Excitation in MnAu due to Femtosecond Spin-Transfer Torques
Markus Weißenhofer, Francesco Foggetti, Ulrich Nowak +1
Efficient and fast manipulation of antiferromagnets has to date remained a challenging task, hindering their application in spintronic devices. For ultrafast operation of such devi…
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…
