Mössbauer spectra measured at 10 K under an applied field of 8 T for samples MAG1 (a), MAG2 (b), MAG3 (c), and MAG4 (d). A sum of two sextets, one for the tetrahedral (red line) and one for the octahedral (blue line) component of the spectra, have been fitted to the experimental data (circles). A black line describes the total fit to the experimental data (grey circles)
