Ru-99 and Fe-57 Mossbauer spectroscopic studies were carried out on te
rnary intermetallic compounds containing ruthenium, Fe3-xRuxSi, within
the concentration range 0.1 less-than-or-equal-to x less-than-or-equa
l-to 1.5. Magnetization of the samples was also measured in the temper
ature range between 4 K and room temperature. Ru-99 Mossbauer spectra
of x = 0.5 and 1.0 were fitted satisfactorily with a broad component o
f H(hf), the peak positions of which were 340 and 270 kOe, respectivel
y.
