Investigating the physical, electrical, mechanical, and electrochemical characteristics of magnetic nanoparticles (CuFe 2 O 4 ) is much needed for choosing materials for making devices in new inventions. The physical characteristics, determined by X-ray diffraction, include the hopping distance between sites A and B (L A and L B ), the distance between two sites A (dL A ), two sites B (dL B ), the distance between sites A and B (dL AB ), and other related distances. The optical behavior is studied through UV-visible spectroscopy analysis. The microscopic and magnetic properties, analyzed through Fourier Transform Infrared (FTIR) spectroscopy and Vibration Sample Magnetometer (VSM) studies, cover aspects such as the force constant, bond lengths between cations and anions etc. The VSM studies reveal a higher magnetic saturation (Ms = 35.72) at 0.3. The dielectric related properties such as dielectric constant, loss, resistivity, and electric modulus, and additionally, the mechanical properties, including the stiff constants C 11 and C 12 , which encompass various mechanical properties, are discussed. The dielectric and electrochemical properties are also explored through impedance analyser and cyclic voltameter measurements.
