Coercivity and exchange bias in size reduced iron obtained through chemical reduction

•Cubic iron particles in a vast average size range have been obtained through polyol process.•Saturation magnetization upto 211 emu/g has been obtained for particles of average size 210 nm.•Coercivity increases to 328 Oe with decreasing particle size upto 50 nm.•Core-shell Fe nanoparticles exhibit e...
