The spin and lattice dynamics of antiferromagnetic bulk Cr 2 O 3 after excitation with an
intense laser pulse were investigated using amplitude and phase resolved optical second-
harmonic generation as probe of the magnetic and crystallographic subsystems.
Demagnetization occurs on three time scales ranging from⪡ 1 to∼ 7 ps. In comparison to
ferromagnetic compounds, this is a two orders of magnitude faster response and an
additional spin-lattice interaction channel is observed.
