? 2022 Elsevier B.V.In this study, a sonochemical reactor was used to synthesize Mn1?xCuxLa0.1Fe1.9O4 nanoferrites with different compositions of x (0.09, 0.18, 0.27, and 0.36). Mn1?xCuxLa0.1Fe1.9O4 nanoferrites were subjected to X-ray diffraction (XRD), field-emission scanning electron microscopy (FESEM), vibrating sample magnetometer, and electrochemical impedance spectroscopy to investigate their magnetic, electrical, and structural properties. Formation of a cubic crystalline structure was observed by the XRD patterns. The decreases in crystalline size could have been caused by an increase in Cu2+ ions in Mn1?xCuxLa0.1Fe1.9O4 nanoferrites. The impedance analysis revealed the presence of pseudocapacitance and resistive behavior in Mn1?xCuxLa0.1Fe1.9O4 nanoferrites. The hysteresis loops promoted the soft ferromagnetic behavior present in Mn1?xCuxLa0.1Fe1.9O4 nanoferrites. A decrease in saturation magnetization and an increase in coercivity were observed with an increase in the Cu2+ content of Mn1?xCuxLa0.1Fe1.9O4 nanoferrites.
