The serial sectioning technique was used to investigate the diffusion of 54Mn in single crystals of undoped and Mn-doped material. The data for undoped samples at temperatures ranging from 213 to 300C could be described by:

D (cm2/s) = 5.34 x 10-4 exp[-0.80(eV)/kT]

The data for undoped samples at temperatures ranging from 300 to 430C could be described by:

D (cm2/s) = 7.71 exp[-1.27(eV)/kT]

The data for doped (2.1mol%Mn) samples at temperatures ranging from 200 to 320C could be described by:

D (cm2/s) = 2.1 x 10-2 exp[-0.56(eV)/kT]
