Description
A polycrystalline sample with the nominal composition RhFe3C was synthesized and its properties were investigated using powder x-ray diffraction (XRD), transmission Mössbauer spectroscopy and heat capacity Cp(T) measurements. The XRD data shows that RhFe3C has a cubic structure with a lattice parameter of 5.8907(3) Å. The room temperature Mössbauer spectrum of RhFe3C exhibits magnetic structure with three spectral components assigned to three different iron sites. The site assignments will be discussed in detail. The Cp(T) data show a distinct behavior and can be fitted with the Debye model with an additional Einstein term. The extracted fitted value of the Debye temperature was determined as 371(1) K. The results obtained from the different experiments will be discussed and compared with literature.
