Abstract

The spin and lattice dynamics of antiferromagnetic bulk Cr2 O3 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.
