We present time-dependent, self-consistent diffusion calculations for Cr, Mn and Fe in a Teff = 12 000 K and logg = 4.0 stellar atmosphere. The temporal evolution of the chemical stratifications is followed for the zero field case and for magnetic fields of varying strength and direction relative to the stellar surface. Preliminary conclusions are preceded by a comparison of the present results to equilibrium solutions.
