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…
