摘要：

For the first time, a study of hyperfine interactions in metal grains extracted from ordinary chondrite Tsarev L5 was done using Mossbauer spectroscopy with high-velocity resolution. Three magnetic (sextets) and one paramagnetic (singlet) components were revealed in the Mossbauer spectrum of extracted metal. The evaluated values of the magnetic hyperfine field were 332.5, 335.4 and 347.2 kOe. On the basis of Mossbauer parameters and metallographic data, the magnetic components were related to the alpha-Fe(Ni, Co), alpha'-Fe(Ni, Co) and alpha(2)-Fe(Ni, Co) phases of Fe(Ni, Co) alloy, while the paramagnetic singlet was related to the gamma-Fe(Ni, Co) phase.
