Morphologies and magnetic properties of FeCo nanoparticles modulated by changing the types of ligands of Co

► FeCo nanoparticles have been prepared using co-precipitation from new precursors. ► Magnetic properties of the FeCo nanoparticles were investigated. ► The magnetic properties of products were dependent on the type of precursor. ► The maximum values of coercivity were obtained 480 Oe.
