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…
Soft-mode nonlinearities away from ferroelectric phase transition
Payel Shee, Ipek Efe, Jingwen Li +3
The interplay between ionic and electronic subsystems dictates the behavior of structural phase transitions in polar dielectrics, a coupling mediated by soft optical phonon modes.…
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…
Magnetoelectric phase control at domain-wall-like epitaxial oxide multilayers
Elzbieta Gradauskaite, Chia-Jung Yang, Shovon Pal +2
Ferroelectric domain walls are nanoscale objects that can be created, positioned, and erased on demand. They often embody functional properties that are distinct from the surroundi…
