Magnon chiral damping beyond the Dzyaloshinskii-Moriya interaction
Darpa Narayan Basu, Subhadip Ghosh, Peter M. Oppeneer +2
Magnon chiral damping denotes damping that is asymmetric with respect to the magnon wave vector. Such nonreciprocity has been attributed to antisymmetric Dzyaloshinskii-Moriya spin…
Momentum-dependent precessional and nutational spin pumping in a honeycomb antiferromagnet
Suman Mukherjee, Subhadip Ghosh, Ritwik Mondal
The ultrafast magnetic inertial dynamics on subpicosecond timescales generate an additional high-frequency terahertz nutational resonance. Here, we investigate momentum-resolved sp…
The interplay of crystal-field transitions and exchange spin dynamics in a ferrimagnet
Arpita Dutta, Pratyay Mukherjee, Ritwik Mondal +1
Rare-earth iron garnets offer an ideal platform for exploring the interplay of low-energy excitations and the complex temperature-dependent magnetization dynamics. In these systems…
Relativistic theory for coupled orbital and spin angular momentum dynamics in magnetic systems
Subhadip Santra, Ritwik Mondal, Marco Berritta +1
We develop a complete relativistic theory to describe the dynamics of electronic angular momentum including both spin (S) and orbital (L) contributions in magnetic systems. We star…
Spin Inertia as a Source of Topological Magnons: Chiral Edge States from Coupled Precession and Nutation
Subhadip Ghosh, Mikhail Cherkasskii, Ritwik Mondal +2
Spin inertia has been demonstrated to give rise to high-frequency nutational excitations beyond the conventional low-frequency precessional modes. Here, we demonstrate that the hyb…
Unquenched orbital angular momentum as the origin of spin inertia
Tarek Moussa, Darpa Narayan Basu, Ritwik Mondal +1
The recent proposal and observation of spin inertia, and the consequent high-frequency spin nutation mode, have raised key questions for our understanding of magnetization dynamics…
Ultrafast switching of antiferromagnetic order by field-derivative torque
Pratyay Mukherjee, Ritwik Mondal
Control of magnetic order in antiferromagnets is a central challenge in the development of next-generation spintronic devices. Here, we propose and analyze magnetization switching…
