Abstract
- The effect of Cr[sup 3+] concentration on the various hyperfine interactions for the ferrite system Li[sub 0.5+t]Cr[sub x]Sb[sub t]Fe[sub 2.5-2t-x]O[sub 4], 0.0 ≤ x ≤ 1.0, x in steps of 0.2 and t = 0.1, have been studied at room temperature using Mössbauer spectroscopy. The isomershift and the quadrupole splitting are almost negligibly influenced by the change in chromium level. The internal nuclear magnetic fields as determined from the Mössbauer spectra and the linewidth are also studied with the variation of composition. The results have been explained on the basis of various models and a cation distribution has been worked out. [ABSTRACT FROM AUTHOR]
