Role of material-dependent properties in THz field-derivative-torque-induced nonlinear magnetization dynamics
Arpita Dutta, Pratyay Mukherjee, Swosti P. Sarangi +3
The traditional Landau-Lifshitz-Gilbert (LLG) equation has often delineated the linear and nonlinear magnetization dynamics, even at ultrashort timescales e.g., femtoseconds. In co…

Evidence of relativistic field-derivative torque in nonlinear THz response of magnetization dynamics
Arpita Dutta, Christian Tzschaschel, Debankit Priyadarshi +4
Understanding the complete light-spin interactions in magnetic systems is the key to manipulating the magnetization using optical means at ultrafast timescales. The selective addre…
