A correlation between the growth process and electrical properties of [Ni_{80}Fe_{20}(2 nm)/Au(2 nm)/Co(0.8 nm)/Au(2 nm)]_{15} multilayers is presented. A set of multilayers of identical composition was deposited in different temperatures. The changes in giant magnetoresistance amplitude were correlated with the changes in Co layers growth process that occur in different temperatures. The in situ conductance measurement leads to the growth mechanism identification in high temperatures as formation of Co islands. Intensified islandisation of Co was eventually confirmed by the temperature changes in shape of the Hall voltage loops, and the evolution of Co layers contribution.
