Engineering spin-wave spectrum via the magnetization inertia tensor
Subhadip Ghosh, Darpa Narayan Basu, Ritwik Mondal
Magnetic inertial dynamics has recently been predicted and experimentally demonstrated in two-sublattice ferromagnets such as CoFeB and NiFe permalloy. In this work, we investigate…

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…
