Mössbauer spectroscopy and X-ray diffraction have been used to study three series of electrodeposited alloys: Fe-Ni, Fe-Co and Co-Ni, doped with ⁵⁷Fe. The crystalline structure of electrodeposited Fe-Ni and Fe-Co alloys changes at the concentration of the given element dissolved in Fe a little different from that for thermally prepared alloys. The changes of the average hyperfine magnetic field and the average isomer shift are determined as a function of the changes in the average number of atoms in the nearest neighbourhood of ⁵⁷Fe.
Electrodeposited alloys have an interesting feature i.e. the isomer shift of the alloy changes its sign, relative to the isomer shift for pure iron. It may be connected with internal stresses in the deposited alloy.
