Abstract:
An ultrashort magnetic field pulse generated by a laser pulse can excite spin oscillations in a “pure” antiferromagnet even when a weak ferromagnetic moment is absent. This mechanism features the spin oscillation amplitude independent of the sublattice structure and parameters of the ferromagnet and is governed only by the field pulse parameters.
