Abstract :
This work explores the nanostructure dependence of extraordinary Hall effect (EHE) in Cu80Co20 granular thin films. Upon annealing, an unusual nanostructure evolution in Cu-Co into two Co particles-size distribution affects the magnetotransport properties, most evidently in the EHE. It was concluded that the EHE in annealed films primarily depends on the population of smaller sized particles. Upon annealing, the EHE field sensitivity was gradually reduced from 0.78 nOmega-cm/Oe for the as-deposited film to 0.04 nOmega-cm/Oe for 400degC annealed one
