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…
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…
Engineering spin-wave spectrum via the magnetization inertia tensor
Subhadip Ghosh, Darpa Narayan Basu, Ritwik Mondal
Magnetic inertial dynamics has recently been predicted and experimentally demonstrated in two-sublattice ferromagnets such as CoFeB and NiFe permalloy. In this work, we investigate…
Theory of tensorial magnetic inertia in terahertz spin dynamics
Subhadip Ghosh, Mikhail Cherkasskii, Igor Barsukov +1
Magnetic inertia has emerged as a possible way to manipulate ferromagnetic spins at a higher frequency e.g., THz. Theoretical treatments so far have considered the magnetic inertia…
