Abstract

The work investigating the effect of saccharine as an additive on growth stress and structure of electrodeposited CoFe films is presented. The saccharine concentrations were in the range between 0 gL^(-1) and 1.5 g^(L-1). The stress measurements are performed insitu during electrodeposition process of CoFe films using cantilever bending method (curvature measurements). The structure of CoFe films was studied by transmission electron microscopy and X-ray diffraction measurements. Results show that growth stress is a decreasing function of saccharine concentration. No appreciable change in composition, grain size, orientation or texture of CoFe films is observed with increasing saccharine content in solution. The growth stress dependence on saccharine concentration is discussed within the framework of developed analytical model which directly links the observed stress decrease in electrodeposited CoFe films with the apparent saccharine coverage of the CoFe film surface during electrodeposition process.
