Abstract
Iron-based superconductors can exhibit different magnetic ground states and are in a critical magnetic region where frustrated magnetic interactions strongly compete with each other. Here we investigate the longitudinal modes of spin fluctuations in a unified effective magnetic model for iron-based superconductors. We focus on the collinear antiferromagnetic phase and calculate the behavior of the longitudinal mode when different phase boundaries are approached. The results can help to determine the nature of the magnetic fluctuations in iron-based superconductors.
