Ternary metal oxide (FeCoCrO4) nanoparticles were synthesized using simple and straightforward co-precipitation method. Different green extracts from ginger and Malva sylvestris were used as green capping agents. The composition and phase structure of the synthesized nanoparticles were studied using X-ray diffraction pattern (XRD), confirming the formation of cubic structure. The potential of steric stabilization of the nanoparticles using the used green capping agents reflected in reduction of calculated lattice parameters, average crystallite size, and particle size. The magnetic properties of the synthesized nanoparticles were investigated using vibrating sample magnetometer (VSM), which revealed ferromagnetic behavior. The size dependence of magnetic parameters, including saturation magnetization (Ms), coercivity (Hc), remnant magnetization (Mr), anisotropy constant, and magnetic moment, was determined. The reduction in these parameters was observed for the nanoparticles synthesized in the presence of the green capping agents. The Ms for the aqueous-media-synthesized nanoparticle was 88.9 emu/g, which reduced to the 29.5 and 43.4 emu/g for those synthesized in ginger and Malva sylvestris extracts, respectively. The decrement of Hc and Mr with reducing of the particle size confirmed the decrease in magnetic domain size as the result of using the green capping agents.
