Some time ago it has been recognized from pump probe laser experiments that magnetic dynamics can be triggered and monitored on time scales much shorter than the previously considered limit of spin-lattice relaxation (nanoseconds). We will give an overview on the various contributions to ferro- and anitferromagnetic spin dynamics on the subpicosecond timescale. We will demonstrate the role that quantum chemical ab-initio theory can play in this field. Furthermore we will emphasize the essential role of spin-orbit coupling which in combination with the laser field leads to spin dynamics. Specifically we will address the effects of spin-dependent bleaching, magnetic dephasing and ultrafast laser induced demagnetization in ferromagnetic nickel and its (001) surface, as well as all-optical magnetic switching on the (001) surface of NiO.
