Effect of photoexcited carrier density on spin diffusion coefficient and helical spin lifetime
We investigate the effect of the photoexcited carrier density on helical spin dynamics using time- and spatially resolved magneto-optical Kerr rotation measurements. The helical spin lifetime is extended by increasing the photoexcited electron spin density because the phase decoherence by spin prece...
