Copper substitution effect on the structural, electrical, and magnetic properties of manganese and lanthanum (Mn1−Cu La0.1Fe1.9O4) nanoferrites
Source abstract
Abstract
In this study, a sonochemical reactor was used to synthesize Mn 1−xCu xLa 0.1Fe 1.9O 4 nanoferrites with different compositions of x (0.09, 0.18, 0.27, and 0.36). Mn 1−xCu xLa 0.1Fe 1.9O 4 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 Cu 2+ ions in Mn 1−xCu xLa 0.1Fe 1.9O 4 nanoferrites. The impedance analysis revealed the presence of pseudocapacitance and resistive behavior in Mn 1−xCu xLa 0.1Fe 1.9O 4 nanoferrites. The hysteresis loops promoted the soft ferromagnetic behavior present in Mn 1−xCu xLa 0.1Fe 1.9O 4 nanoferrites. A decrease in saturation magnetization and an increase in coercivity were observed with an increase in the Cu 2+ content of Mn 1−xCu xLa 0.1Fe 1.9O 4 nanoferrites.
