Synthesis and characterization of Co-Fe nanocrystalline magnetic films electrodeposited from electrolyte solution containing sodium saccharin

Cobalt-iron (Co-Fe) alloy thin films (Co100-x-Fex with x=0 , 6, 11, 14 and 18) were electrodeposited on brass substrates from sulfate plating baths containing saccharin salt. The electrolyte in the synthesis process consists of mixtures of FeSO4.7H2O , CoSO4.6H2O, NaCl and H3BO3. Various concentrati...
