1.6 K Mössbauer spectra for (top), (middle), and (bottom). All three samples clearly exhibit splitting due to the presence of a transferred magnetic field at the two Sn sites in the structure.
Temperature dependence of the transferred hyperfine fields in (top) and (bottom), each fitted with Brillouin functions. The site assignments for are discussed in the text.
Temperature dependence of the transferred hyperfine magnetic fields in . The solid lines are Brillouin function fits to the points below 8 K. The Sn (◻) and Sn (○) site assignments are only considered valid below (see text).
Room temperature lattice parameters, quadrupole splittings in the paramagnetic state, and the transferred hyperfine magnetic fields at each site obtained at 1.6 K.
