A previous paper reported that Mn2+ impurities contained in NaCl tend to migrate from the volume to the surface when the crystals are heated to temperatures between 400° and 550°C in air. Once on the surface, the impurities react with oxygen and an epitaxial oxide film is produced on the NaCl substrate. In the present work new data about this oxide film are reported. It has been found that diffusion to the surface can also be observed for KCl:Mn2+, LiF:Mn2+ and LiCl:Mn2+ crystals, at several impurity concentrations, and when heating is carried out in a vacuum of 10-6 torr. It is shown that this effect has a strong influence in the epitaxy of metal films on alkali halide substrates.
