Crystallographic and magnetic phase stabilities of NiFe2O4 nanoparticles at shocked conditions

In the present article, we have reported the crystallographic and magnetic phase stabilities of nickel ferrite nano particles (NiFe₂O₄ NPs) at different number of shock wave-loaded conditions. Series of shock pulses have been loaded on the test samples such as 50,100 and 150 shock pulses with Mach number 2.2. Powder X-ray diffractometer (XRD), diffused reflectance spectroscopy (DRS) and vibrating-sample magnetometer (VSM) are utilized to examine the crystallographic, electronic and magnetic phase stabilities. The observed XRD, DRS and VSM results indicated that no crystallographic, electronic and magnetic phase transitions occurred by the impact of shock waves. Fascinatingly, SEM images show the shock wave assisted shape modification at 150 shocks. The accomplished magnetic phase stability results have compared with our previous report on Fe₂O₃ NPs for better understanding the structure-property stabilities of title ferrite against the impact of shock waves. Based on the observed results, we wish to suggest that the title material is a suitable candidate for high pressure, high temperature applications and for aerospace applications due to the outstanding shock resistance properties.
