Anomalies of Ultrasonic Velocities and Elastic Properties in R1-XAXMnO3 Perovskite Manganite Materials

In this research work, the scholar prepared mixed valent perovskite materials with the general formula La_1-XA_XMnO₃ (A-calcium, sodium and gadolinium) with different values of x using solid state reaction technique. He explored the structural and morphological characteristics such as crystal structure, crystalline size and size of particles of the prepared samples employing studies such as x-ray diffraction (XRD)and scanning electron microscope (SEM). He confirmed the elemental composition of the prepared perovskite samples with the obtained energy dispersive x-ray spectrometrypatterns.
