Notes:
Magnetization and 57Fe Mössbauer studies have been made in Fe3−xRuxSi for 0≤x≤2. Up to x=1.35, the alloys behave like collinear ferromagnets and μ/f.u. and HF (Fe) values do not show any appreciable change, thus suggesting that Ru replacing magnetic Fe (A,C) atoms also possess a large moment of ∼1 μB. For x〉1.35, the approach of magnetization to saturation becomes progressively slower and the system acquires an inhomogeneous magnetic structure. In the region 1.45 ≤x〈1.8, Tm and Thf, the HF (Fe) evolution temperature, fall rapidly, with Thf(very-much-less-than)Tm resulting in a behavior a la RuFeSi. For x〉1.8, majority of the Fe atoms are on B site and they presumably undergo AF/random freezing. Even though Tm and magnetization behavior show considerable variation across the region 1≤x≤2, the character of Mössbauer spectra does not change and 〈HF (Fe)〉av measured at 4.2 K remain ∼250 kOe.
