Abstract

The paper reports the57Fe Mössbauer effect investigations on the solid solutions of Li0.5ZnxTixFe2.5−2xO4 (x=0 to 0. 6) at 300K. The samples with x⩽0.4 exhibit well defined Zeeman pattern consisting of two sextets corresponding to Fe3+ ions at tetrahedral and octahedral sites. The composition with x=0.5 shows a strong ferrimagnetic relaxation whereas the composition with x=0.6 exhibits paramagnetic behaviour. The internal magnetic field at57Fe nuclei decreases with increasing x at both the sublattices. This variation is explained in terms of cation distribution and super-exchange interactions. The s-electron density has been observed to be independent of substitution level.
