HYPERFINE INTERACTION STUDIES OF Co2+ SUBSTITUTED Li-Sb FERRITE SYSTEM

Abstract

Mössbauer investigations have been carried out for the system Li 0.6-0.5x Co x Sb 0.1- Fe 2.3-0.5x O 4 with 0.0≤x≤1.0, x in steps of 0.2. The observed variation of the various Mössbauer parameters like isomershift, quadrupole splitting, nuclear magnetic field and linewidth are explained in terms of cation distribution and superexchange interaction.
