“…Consequently, the Mössbauer spectroscopy together with the XRD reveal that it was succeeded to prepare an amorphous Fe-P alloy layer using pulse plating method. The hyperfine field value of pulse plated Fe-9 wt.% P alloy from group 1 is smaller than that observed previously [11,12], indicating differences in the short range ordering due to the different preparation routes.…”

“…This spectrum can be considered as a superposition of a large number of sextets having different hyperfine parameters due to iron atoms being in slightly different surroundings in the amorphous alloy. The average Mössbauer parameters, shown in Table I, roughly correspond to those of Fe-P amorphous alloys prepared by dc electrodeposition or rapid quenching in the corresponding composition range [11,12]. Consequently, the Mössbauer spectroscopy together with the XRD reveal that it was succeeded to prepare an amorphous Fe-P alloy layer using pulse plating method.…”

“…The P content of this sample was found to be 9.0±0.1 wt.%. At this composition the formation of the amorphous phase can also be obtained both with rapid quenching and also by conventional electrodeposition methods [11,12].…”

57 Fe conversion electron Mössbauer spectroscopy, X-ray diffraction, electrochemical and magnetic measurements were used to study pulse electroplated Fe-P and NiFe coatings. XRD and 57 Fe CEMS measurements revealed the amorphous character of the novel pulse plated Fe-P alloys. CEM spectra indicated significant differences in the short range order and in the magnetic anisotropy between the Fe-P deposits pulse plated at medium long deposition time (t on =2 ms), with short relaxation time (t off =9 ms) and low current density (I p =0.05 Acm −2 ) or at short deposition time (t on =1 ms) with long relaxation time (t off =250 ms) and high current density (I p =1.0 Acm −2 ). The broad peaks centred around the fcc reflections in XRD of the pulse plated Ni-22 wt.% Fe deposit reflected a microcrystalline Ni-Fe alloy with a very fine, 5-8 nm, grain size. The CEM spectrum of the pulse plated Ni-22 wt.% Fe coating corresponded to a highly disordered solid solution alloy containing a minute amount of ferrihydrite. Extreme favourable soft magnetic properties were observed with these Ni-Fe and Fe-P pulse plated thin layers.
