Structural and temperature dependent dielectric properties of doped Mn ferrite system

open access: yesChemical Physics Impact, 2023
In this work, we have synthesized the Mn1-xAxFe2O4 (A = Zn, Cr; x = 0.5) ferrites. The synthesis of nanoparticles is done with the help of a low temperature gel autocombustion method. Structural confirmation of the nanoparticles is performed by the X-ray
