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}…
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…
Search for large topological gaps in atomic spin chains on proximitized superconducting heavy metal layers
Philip Beck, Bendegúz Nyári, Lucas Schneider +7
One-dimensional systems comprising s-wave superconductivity with meticulously tuned magnetism and spin-orbit coupling can realize topologically gapped superconductors hosting Major…
Testing the topological nature of end states in antiferromagnetic atomic chains on superconductors
Lucas Schneider, Philip Beck, Levente Rózsa +3
Edge states forming at the boundaries of topologically non-trivial phases of matter are promising candidates for future device applications because of their stability against local…
Temperature dependence of spin-model parameters in antiferromagnets
Levente Rózsa, Unai Atxitia
The temperature dependence of mesoscopic spin-model parameters is derived in two-sublattice antiferromagnetically aligned systems based on Green's function theory. It is found that…
Inertial spin waves in ferromagnets and antiferromagnets
Ritwik Mondal, Levente Rózsa
Inertial effects in spin dynamics are theoretically predicted to emerge at ultrashort time scales, but their experimental signatures are often ambiguous. Here, we calculate the spi…
Nutational switching in ferromagnets and antiferromagnets
Lucas Winter, Sebastian Großenbach, Ulrich Nowak +1
It was demonstrated recently that on ultrashort time scales magnetization dynamics does not only exhibit precession but also nutation. Here, we investigate how nutation can contrib…
