57Fe Mössbauer spectra of YbFe4Al8 of the tetragonal ThMn12 structure have been investigated. Mössbauer measurements at the lowest temperatures yield information on the iron population in three crystallographic sites 8f, 8j and 8i available for Fe atoms. The obtained results indicate on the coexistence of magnetically ordered and paramagnetic-like Fe moments within antiferromagnetic phase of YbFe4Al8. The MS measurements show that the onset of short range antiferromagnetic interaction in the Fe sublattice takes place at 220 K.
