Fig. 1: A simple model of spin dynamics begins by picturing magnetic ordering as an arrangement of arrows.
Fig. 2: A Heisenberg model with a thickness-dependent interaction parameter is used to fit experimental spin-wave data determined from resonant inelastic X-ray scattering experiments on thin ferromagnetic iron films.
