摘要：

Lithium manganese nanoferrites (LixMn1-2xFe2+xO4, x = 0.0, 0.1, 0.2, 0.3, 0.4) are prepared by the chemical coprecipitation method. Magnetic properties of as-synthesized samples are investigated at room temperature using a vibrating-sample magnetometer. The superparamagnetic behavior of the samples is observed on the recorded M-H curves. From the hysteresis curve, saturation magnetization, coercivity, and retentivity are obtained. The squareness ratio, anisotropy constant and magnetic moment of the samples are calculated and compared. The cyclic voltammetry analysis is performed for different scan rates to determine the specific capacitance. The energy density and power density are calculated from the charge-discharge curve. The resistance to selected bacteria is analyzed using the antimicrobial activity test
