“…4. This type of Mössbauer spectrum is common in most of the nanosize zinc ferrite system which is attributed to superparamagnetic character and discussed in detail by previous workers [11,[14][15][16]. The spectra obtained in the present case were least square fitted and the refined values of hyperfine parameters are plotted in Fig.…”

Nanosize zinc ferrite particles, prepared by nitrate method, were investigated by XRD, TEM, 57 Fe Mössbauer spectroscopy and VSM. The average particle size in this system varies from 10 to 62 nm as the sintering temperature increases from 300 • C to 1,000 • C. The lattice parameters in this system are almost constant at a value of ∼8.41 Å. The Mössbauer spectra of all the sintered samples show a single doublet. The Mössbauer hyperfine parameters show little change with the change of sintering temperature. The doublets are ascribed to the presence of superparamagnetism in this system, which is also corroborated by the VSM measurements.

“…The corresponding hyperfine field distribution (P(B hf )) is shown at the right hand side of each spectrum. The M€ ossbauer results are in trend with that of the earlier published results [5]. The M€ ossbauer spectrum of the pure MnFe 2 O 4 sample (Z1) exhibits a sextet with broad lines and a central doublet.…”
