Abstract

Presented work investigates conditions at the electrode/solution interface leading to incorporation of Fe(OH)₃ into CoFe thin films. The oxygen content and coercivity of CoFe films is studied as a function of Fe³⁺ ion concentration in the solution. These results are analyzed through the scope of analytical model describing the oxygen presence in CoFe films as a consequence of Fe(OH)₃ incorporation phenomenon. The scanning transmission electron microscopy study with nanometer scale resolution for composition analysis has elucidated the alteration in grain structure of CoFe films due to Fe(OH)₃ incorporation. These findings directly implicate Fe(OH)₃ incorporation as a reason for the increase in coercivity of CoFe films.
