Abstract

We present time-dependent, self-consistent diffusion calcu- lations for Cr, Mn and Fe in a Teff = 12000K and log g = 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 con- clusions are preceded by a comparison of the present results to equilib- rium solutions.
