Effect of Ti4+ substitution on the hyperfine properties of Li–Sb–Ti ferrites using Mössbauer spectroscopy
Mössbauer investigations were carried out at room temperature on the ferrite system Li0.6 + 0.5tFe2.3 − 1.5tTitSb0.1O4 (0.0 ≤ t ≤ 1.0 in steps of 0.2). The effect of Ti4 + concentration on the various hyperfine interactions like Isomer shift, quadrupole splitting and internal magnetic field have been studied. The spectra exhibited well-defined Zeeman sextets at low substitution level, corresponding to the A and B sites. The sample with t = 1.0 showed paramagnetic behaviour. The results obtained have been discussed.
