Abstract
CoWP alloy films were prepared by a typical citrate system electrodeposition on a copper substrate. The paper investigated effects of different temperatures on codeposition mechanism, magnetic property, component and structure of CoWP alloy films during the electrodeposition process. With the increase in temperatures, deposition rate and thickness rose gradually during the electrodeposition process. It was found that higher temperature improved contents of phosphorus and tungsten but reduced amounts of cobalt in the films. Almost all the deposited films were crystalline and formed tetrahedral structures Co3W with preferred crystallographic orientation (200) and (201). Films of dissimilar surface morphology could be observed under different temperatures. Lower saturation magnetisation and higher coercivity of CoWP films could be obtained at higher temperatures.
