FIG. 5. Global (a) spin and (b) energy variation in Fe6 for two different excitations differing only by the direction of polarization of the electric-field pulse. Cartoon of the cluster with labels of the relevant atoms and a reference frame are depicted as insets. The contour plots represent (c) and (e) the distribution of the angle between m and Bkin in a plane through atoms 1, 3, 5, and 6 (as in Fig. 3) and (d) and (f) the perpendicular component of m with respect to Bkin averaged over the time of the simulation, for the two different excitations (a), (c), and (d) E‖x and (b), (e), and (f) E‖z.
