We study the dependence of the spectral gap for the generator of theGinzburg-Landau dynamics for all \emph{$\mathcal O(n)$-models} with mean-fieldinteraction and magnetic field, below and at the critical temperature on thenumber $N$ of particles. For our analysis of the Gibbs measure, we use aone-step renormalization approach and semiclassical methods to study theeigenvalue-spacing of an auxiliary Schr\"odinger operator.
