Abstract

Calcium doped nickel ferrite (Ni1-xCaxFe2O4; x = 0.0, 0.1, 0.3 and 0.5) nanoparticles (NPs) were prepared by microwave irradiation technique employing the fuel L-arginine. The as prepared compositions were subjected to structural, magnetic and optical properties. Lattice constant increased with increase in calcium concentration. Transmission Electron microscope (TEM) technique provides information about morphology of the synthesized Ni1-xCaxFe2O4 ferrites. Magnetic hysteresis (M-H) loop revealed the magnetic behavior of the prepared spinel Ni1-xCaxFe2O4 NPs. Magnetization, coercivity and retentivity were calculated from vibrating sample magnetometer (VSM) studies. The antibacterial activity was also studied.
