Topological Hall plateau in quasi-2D kagome magnet YMnSn
Sambit Jena, Nastaran Salehi, Manuel Pereiro Lopez +5
We examine the impact of the Dzyaloshinskii-Moriya interaction (DMI) in kagome magnets and show that a predominantly planar DMI together with ferromagnetic exchange stabilizes a di…
Ferroelectrical Switching as a Probe of Quantum Damping in Magnetic Spin Systems
Yuefei Liu, Anna Delin, Olle Eriksson +3
While damped spin dynamics is important for the understanding of magnetic materials, clear signatures of \emph{quantum corrections} to the Gilbert damping mechanism remain elusive.…
Hybrid micromagnetic and atomistic modeling of magnetization dynamics induced by engineered defects
Nastaran Salehi, Olle Eriksson, Johan Hellsvik +1
This study presents a 3D version of multiscale approach for investigating magnetization dynamics in multiscale, hybrid micromagnetic-atomistic simulations. The present work introdu…
Ground-state selection via nonlinear quantum dissipation
Alireza Ataei, Olle Eriksson, Vahid Azimi Mousolou
Finding the ground state of complex quantum systems remains a central challenge in many-body physics, quantum chemistry, and combinatorial optimization, due to the exponential grow…
Mechanical control of magnetic exchange and response in GdRuSi: A computational study
Sagar Sarkar, Rohit Pathak, Arnob Mukherjee +3
We present a systematic computational study of the effect of uniaxial strain on the magnetic properties of GdRuSi, a centrosymmetric material known to host a field-induced…
Unveiling Mysteries of GdRuSi: 3D Magnetism in a layered like Magnet
Sagar Sarkar, Rohit Pathak, Arnob Mukherjee +3
GdRuSi, a centrosymmetric magnet with a square lattice of Gd atoms, hosts a short-period skyrmion square lattice (SkL) without Dzyaloshinskii-Moriya interaction (DMI). RKKY…
