- Descripción
- In this paper we report on variable temperature Mössbauer spectroscopy measurements on samples of carbonaceous chondrites Yamato 82162 and Yamato 86720. Transmission Mössbauer spectra were taken through the temperature range <math>4.2 K\,\!</math> to <math>300 K\,\!</math>. The Mössbauer spectra at room temperature indicate in both meteorites the presence of a magnetically splitted component and two quadrupole doublets corresponding to paramagnetic <math>Fe^{2+}\,\!</math> and <math>Fe^{3+}\,\!</math> compounds.
