The ribbon-like samples were annealed at 695 K for 1 and 5 hours before the diffusion experiments; the volume fraction of crystalline phase was checked by the Mössbauer spectroscopy. Concentration profiles obtained by sputtering by Ar+ ions in a glow discharge show two distinct branches suggesting that two diffusion paths are operating. Arrhenius plot of measured diffusion coefficients was not linear in the whole temperature studied interval, which may be due to predominance of less energetically demanding jumps at lower temperatures and higher effective activation enthalpy at higher temperatures. The kink temperature was about 630 K. Workplace Institute of Physics of Materials Contact Yvonna Šrámková, sramkova@ipm.cz, Tel.: 532 290 485 Year of Publishing 2006
