Effects of interlayer Dzyaloshinskii-Moriya interaction on the shape and dynamics of magnetic twin-skyrmions
Tim Matthies, Levente Rózsa, Roland Wiesendanger +1
Magnetic skyrmions have been proposed as promising candidates for storing information due to their high stability and easy manipulation by spin-polarized currents. Here, we study h…
Interlayer and interfacial Dzyaloshinskii-Moriya interaction in magnetic trilayers: first-principles calculations
Tim Matthies, Levente Rózsa, László Szunyogh +2
We determine the Dzyaloshinskii-Moriya interaction within and between two magnetic cobalt layers separated by a non-magnetic spacer through ab initio calculations. We investigate d…
Large diversity of magnetic phases in two-dimensional magnets with spin-orbit coupling and superconductivity
Jannis Neuhaus-Steinmetz, Tim Matthies, Elena Y. Vedmedenko +2
We classify the magnetic ground states of a 2D lattice of localized magnetic moments which are coupled to a superconducting substrate with Rashba-spin-orbit coupling. We discover a…
Quantum revivals and magnetization tunneling in effective spin systems
M. Krizanac, D. Altwein, E. Y. Vedmedenko +1
Quantum mechanical objects or nanoobjects have been proposed as bits for information storage. While time-averaged properties of magnetic, quantum-mechanical particles have been ext…
Non-equilibrium finite temperature dynamics of magnetic quantum systems: Applications to spin-polarized scanning tunneling microscopy
Kolja Them, T. Stapelfeldt, E. Y. Vedmedenko +1
We calculate the real time non-equilibrium dynamics of quantum spin systems at finite temperatures. The mathematical framework originates from the -approach to quantum statist…
Interplay between magnetic and spatial order in quasicrystals
E. Y. Vedmedenko, U. Grimm, R. Wiesendanger
The stable magnetisation configurations of antiferromagnets on quasiperiodic tilings are investigated theoretically. The exchange coupling is assumed to decrease exponentially with…
