Ultrafast internal dynamics of chiral domain walls probed by time-resolved XRMS
Dmitriy Ksenzov, Flavio Capotondi, Nicolas Jaouen +7
We measure picosecond dynamics of labyrinthine stripe domains with chiral Néel-type domain walls using time-resolved x-ray resonant magnetic scattering (XRMS). At the stripe-domain…
