The migration of 60Co tracer in (Co0.8Fe0.2)3V was studied by using serial sectioning techniques above and below the critical temperature for ordering. Above the critical temperature, normal diffusion kinetics were found and the results could be described by:

D (cm2/s) = 1.05 x 101 exp[-3.24(eV)/kT]

Below the critical temperature, the depth profiles were anomalous and only approximate diffusivities could be obtained.
