method. The transient reflectivity shows that the band gap is coherently modulated by optical active E 2g -phonons. In the final step, the band gap is coherently excited and the response of the spin system [...] the polarisation, is detected. Again the rotation of polarisation is coherently modulated by the E 2g -phonon and shows an additional incoherent contribution in the antiferromagnetic phase, which is ascribed …
