Using a radiotracer serial sectioning technique, the diffusion of 54Mn in n-type single crystals with a dislocation density of between 103 and 104/cm2 was studied. The diffusivities at 810 and 1280C were 10-6 and 2 x 10-5cm2/s, respectively, and it was deduced that the activation energy for diffusion between 810 and 1280C was 1.3eV. From the results it was concluded that the migration of Mn in the form of Mn was essentially interstitial.
