Title: Concentration Dependence Of Hyperfine Parameters Of Fe-cu Alloys
Author: Socolovsky L.M.
Sanchez F.H.
Abstract: Fe-Cu alloys produced by mechanical alloying were studied by Mössbauer spectroscopy. Room-temperature Mössbauer spectroscopy done on samples of Fex-Cu100-x (10< x< 45) show a change with concentration, from a superparamagnetic doublet to a broad sextet. The isomer shift behavior with concentration is analyzed with a simple model based on the chemical neighborhood. Quadrupole splitting slightly increases with concentration. Hyperfine parameters of high-temperature spectra of concentrated samples follow the behavior observed for the less-concentrated samples. A comparison with the hyperfine parameters of Fe-Cu alloys obtained by sputtering is done.
