Description
Summary:Measurement of the Mossbauer effect of the 37.2 keV *g transition of 121Sb as well as magnetic measurements have been performed to study the structure change near the magnetic-transition temperature in the perovskite compound Ba(In0.5Sb0.5)O3, which was synthesized by the hydrothermal method for the first time. The Mossbauer isomer shift falls in the region of the Sb(V) and reflects some hybridized-orbital behavior. The major component of the quadrupole coupling tensor (eQVzz) changes with temperature, while the asymmetry parameter (*h) is equal to zero. This implies that the structure change occurs and that the central antimony cations move relative to the surrounding oxygen ions along the z-axis of the crystal.
