Raman Spectroscopic and Electrochemical Measurements of Dynamic Shocked MnFe2O4 Nano-crystalline Materials.

Divalent ferrite nano-crystalline materials subjected to shock wave recovery analysis bringing about prolific outcomes have received widespread attention among the materials scientists due to their outstanding contribution that has fueled the enrichment of science involving high-pressure ferrites which act as the focal-point of the current research theme. On those lines, we intend to provide the Raman spectroscopic and electrochemical measurements of manganese ferrite nanoparticles (MnFe₂O₄ NPs) at dynamic shocked conditions. Raman spectroscopic analysis has revealed the stability of the tetrahedral (A-site) and the octahedral (B-sites) sites of Mn²⁺ ions as well as Fe³⁺ ions at shocked conditions. Cyclic-voltammetry (CV-analysis) and impedance spectroscopic measurements of the shocked samples demonstrate the electro-chemical properties of MnFe₂O₄ NPs whose electrical conductivity is found to have reduced while increasing the number of shock pulses. The consolidated results provide the solid evidence that the test sample's crystal structure does not undergo any crystallographic phase transitions or mixed spinel states at shocked conditions.
