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.
