FIG. 1. (a) Typical electric-field pulse used to excite the Fe6 cluster with the black arrow indicating the direction of the field. The fluence of this pulse is 580 mJ/cm2. (b) Time evolution of the z component of Bkin and BX (exchange component of the field), with respect to their values at t = 0 integrated over the system volume μBBtot(t) = μB ∑ I BI(t). (c) Time evolution of the variation of the total magnetization S totz (t) = ∑ I S I z(t) with respect to its initial value. (d) Time evolution on atomic site 6 of the magnetization variation along z and of the electron density variation with respect to its value at t = 0 integrated inside a sphere of radius R = 0.9 Å.
