Popis: | In this study, La0.55Pb0.45MnO3 nanoperovskites has been synthesised with various grain sizes by a solid state reaction method followed by facile ball milling technique. The structural properties of the prepared nanoprovskites have been correlated with influence of grain size. Further, the synthesised nanoperovskite manganite materials with various grain sizes have been systematically studied for ultrasonic longitudinal and shear velocity and attenuation in wide range of temperatures. All the nanoperovskites revealed out an anomalous behaviour in concern with ultrasonic velocities and attenuation towards the phenomenon of phase transition. |
