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 Spin Torque Nano-Oscillators (SNTO) and spin Hall nano-oscillators. We are also working on spin Hall effect, spin pumping, nanoscale tiny objects called magnetic skyrmions which are very recent developments in the field of spintronics.
