Shock wave induced switchable electrical resistance of ZnFe2O4 nanoparticles

Abstract

Shock wave induced switchable phase transition of materials in crystallographic phase and magnetic phase is one of the standout research topics in recent years and such materials are highly favorable for the applications of sensors as well as resistive memories. On this background, we have achieved the switchable magnetic phase transitions from paramagnetic to super-paramagnetic behavior of zinc ferrite nanoparticles (ZnFe2O4 NPs) with respect to the number of shock pulses and this switchable magnetic phase transition is strongly related to the crystal structure of the zinc ferrite nanoparticles and it has been reported elsewhere (Mowlika et al., 2020) [11]. Furthermore, the mechanism of the above mentioned switchable phase transition of the title ferrite has been drawn by making use of Raman spectroscopic results. In addition to that, the switching behavior of the title ferrite is demonstrated considering the obtained values of specific capacitance and electrical resistivity which have been experimented through electrochemical analyses such as cyclic voltammetry (CV) and electrochemical impedance spectroscopy (EIS). Based on the observed analytical results, it is proposed that the title ferrite can be a potential material for sensors, energy storage devices, resistive memories and stress history profiling applications.
