Laser-induced ultrafast demagnetization and perpendicular magnetic anisotropy reduction in a Co${}_{88}$Tb${}_{12}$ thin film with stripe domains

M. Hennes, A. Merhe, X. Liu +15

We use time-resolved x-ray resonant magnetic scattering (tr-XRMS) at the Co M${}_{2,3}$- and Tb O${}_1$-edges to study ultrafast demagnetization in an amorphous Co${}_{88}$Tb${}_{12}$ allo…
