Synthesis and characterisation of nanostructured Co-Pt magnetic films electrodeposited from tartrate-stabilised chloride baths

Cobalt-platinum (Co-Pt) nanocrystalline alloy films were electrodeposited using a novel stable single-bath system containing a complex forming additive which stabilised the Co2+ ions and enhanced codeposition with platinum complexes. The compositions of the electrodeposits was controlled by adjustin...
