Ab-initio study of ultrafast spin dynamics in Gdx(FeCo){1-x} alloys

J. K. Dewhurst, Sam Shallcross, I. E. Radu +3

Using an ultrashort laser pulse we explore {\it ab-initio} the spin dynamics of Gd${}_x$(FeCo)${}_{1-x}$ at femtosecond time scales. Optical excitations are found to drive charge from…
