Intensity-driven Mott-like transition in a 2D Ruddlesden-Popper perovskite
Koushik Mondal, Amit Haldar, Indrajit Mondal +7
Two-dimensional Ruddlesden-Popper-type halide perovskites have emerged as promising cutting-edge nonlinear optical materials due to their strong excitonic effects and carrier-densi…
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…
Field-derivative torque induced magnetization reversal in ferrimagnetic GdYbBiFeO
Pratyay Mukherjee, Arpita Dutta, Somasree Bhattacharjee +2
Understanding the mechanism of spin switching in ferrimagnets via the excitation of THz pulses holds promise for future-generation magnetic memory devices. Such spin switching can…
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…
