Abstract
The magneto-optical response of Fe and CrO2 epitaxial films has been investigated by pump-probe polarimetry, showing that charge and spin dynamics can be unambiguously disentangled. Both diagonal and off-diagonal terms of the dielectric tensor can be retrieved, providing the complete dynamical characterization of magnetic and optical properties in a ferromagnet.

From the dynamics of N, recalling that \( N = \sqrt {\varepsilon_{xx} } \), the time evolution of the diagonal dielectric element \( \varepsilon_{xx} \) can be easily obtained.
