Structural, thermal stability and defect studies of Fe–Ag alloy prepared by electrodeposition technique

Dendritic Ag–Fe nanocrystalline alloy synthesized by pulsed electrodeposition and its characterization

“…The presence of fcc peaks can be attributed to the mixing of Fe atoms whose atomic radius is smaller, into the fcc Ag lattice. Similar formation of fcc structure of Ag-Fe alloy nanomaterials have been reported in literatures [8,13,15]. But, since the peak positions of bcc Fe (1 1 0), (2 0 0) and (2 1 1) are very close to the fcc peaks (2 0 0), (2 2 0) and (3 1 1) of Ag-Fe alloy, they are likely to have submerged.…”

“…Though this system has been prepared by a few methods such as magnetron sputtering, pulsed laser deposition, vapour quenching, sol-gel method, molecular beam epitoxy, etc., and its properties investigated [8][9][10][11][12], reports on its electrodeposition are scarce. The stability of electrodeposited Ag-Fe alloy has been reported by Roy et al [13]. In this work dendrite shaped Ag-Fe alloy nanomaterial is prepared in different compositions by pulsed electrodeposition at different current densities from electrolytes not reported so far.…”

Mössbauer investigation of sputtered Fe Ag100− films

“…As for all values of x the spectra do not show any evident sextet contribution, the magnetic structure of the samples mainly reveals a superparamagnetic [4] character. Due to the very short MS measurement time [5], this means that the samples magnetic structure should be made by very small coherent magnetic regions.…”

Magnetic structure of Fe-Fe oxide nanoparticles made by electrodeposition

“…The line width of sextet components is 0.35 mm/s which is bit larger than the width obtained with our setup in pure phase components (0.28 mm/s). The extra broadening may come due to defect productions which are known to exist in large numbers in electrodeposited materials (Roy et al, 2002;Roy et al, 2004). Together with the sextet we have a doublet component having about 23 % of the total absorption area.…”
