| Abstract: | The Mössbauer spectrum of BaFe4Sn2O11 has been recorded for both 57Fe and 119Sn isotopes at a variety of temperatures. In the paramagnetic state the 57Fe spectra are interpreted in terms of three iron environments. Magnetic ordering begins at 77 K and is virtually complete by 4.2 K to give an average magnetic hyperfine field of 504 kG. The 119Sn spectra also reflect the magnetic ordering and a magnetic hyperfine field of 45 kG is transferred to the tin nuclei. |
