Control of helix orientation in chiral magnets via lateral confinement
Maurice Colling, Mariia Stepanova, Mario Hentschel +7
Helimagnetic materials offer a versatile platform for spin-based device concepts owing to their long-range, tunable spiral order. Here, we demonstrate controlled manipulation of th…

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…
