Differences of isomer shift (listed in Table 3) observed at both temperatures indicate, that carbon enters the bulk of the alloy.

They can be distinguished by hyperfine parameters, namely, isomer shift and quadrupole splitting.
The nuclear hyperfine field, quadrupole splitting, and isomer shift provide very precise information about the electronic and magnetic state of the nuclei, chemical bonds, structure of the local environment, and so on [1, 2].
The isomer shift [delta] is reported with respect to iron metal at ambient temperature and was not corrected in terms of the second-order Doppler shift.
For the samples prepared at temperature [T.sub.calc] = 420[degrees]C and higher, the third spectral component was added which was identified according to its hyperfine parameters (magnetic splitting, isomer shift, and quadrupole splitting) as hematite.
The isomer shift values of two doublets, (0.34 [+ or -] 0.01) mm/s and (0.43 [+ or -] 0.06) mm/s, indicate the presence of the [Fe.sup.3+] ions in two different local environments.
