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.

In the following we present the role of surface scattering at Au/Co and Au/Ni-Fe interfaces in Ni-Fe/Au/Co/Au multilayers deposited in different temperatures. Specularity parameter, which describes the electron scattering, is calculated from fitting in situ collected conductance data with the Fuchs-Namba-Tesanovic model. Application of the parallel resistors model enabled to depict changes between Au/Co and Au/Ni-Fe interfaces within multilayers for each repetition. The correlation between enhanced grain boundary scattering for higher deposition temperatures and surface roughness of Ni-Fe/Au/Co/Au multilayers is found.

An advanced deposition technique known as glancing angle deposition was used to fabricate randomly seeded magnetic cobalt columnar nanostructures. The existence of nanocolumns was confirmed by the cross-section scanning electron microscopy. The evolution in the magnetization reversal mechanism as a function of the film thickness was investigated. The coercivity H_{C} and M_{R}/M_{S} ratio (where M_{R} and M_{S} denote the remanent and saturation magnetization, respectively), derived from the magnetic hysteresis loops, are discussed as a function of the angle between the external magnetic field and the surface normal. The direction of the magnetization easy/hard axis and the columns inclination angle were determined on the basis of the angular dependences of the H_{C} and the M_{R}/M_{S}. A crossover from the coherent rotation, based on the Stoner-Wohlfarth model, to the curling reversal mode was observed.
