Abstract
In this paper we study the dynamics of the two-dimensional Heisenberg antiferromagnet in an external magnetic field at zero temperature, using the memory function formalism. The imaginary part of the memory function, which is related to the damping, shows a one peak structure. The dynamical structure factor shows a smooth peak well defined separated from another very small peak.
