Variation of the Mössbauer hyperfine parameters for the A site as a function of composition across the Mn1-xFexNb2O6 system: (a) isomer shift; (b) quadrupole splitting; (c) total line widths; line widths have been corrected for absorber thickness effects. The line width for the absorber thickness ta = 2 has been calculated according to Margulies & Ehrmann (1961). |
