Resumen:
A study of the hyperfine properties of the fcc and hcp phases
of the FeMn and FeMnSi systems, performed on a systematic
and accurate set of samples belonging to the 15 at%
to 30 at% Mn and 0 at% to 12 at% Si composition ranges, is
presented. The samples were characterized using Conversion
Electron Mössbauer Spectroscopy. The evolution with the
Mn and Si contents of the hyperfine parameters of both
phases has been determined. A constancy of the isomer shift
parameter of the hcp phase with both constituents of the alloy
was observed. While constancy and a linear decrease of the
isomer shift values of the fcc phase with Mn and Si, respectively,
were determined. The magnetic hyperfine field of the
fcc phase presents two different values depending on the Mn
content in the binary system and a decrease with the addition
of Si when the ternary alloy is considered.
