Spin Dynamics Lab
Department of Physics, IIT Delhi
Welcome to the spin dynamics lab ! We are working on nanomagnetism and spintronics with emphasis on spin torque induced magnetization dynamics. We are interested in the study of magnetization dynamics at the nanoscale, with a focus on topological quantum materials. We are also working on spin Hall effect, spin pumping, magnetization switching, and nanoscale tiny objects called magnetic skyrmions which are very recent developments in the field of spintronics.
