•Room-temperature ferromagnetism was observed in Fe2+-doped ZnSe microspheres.•Transition from ferromagnetism to superparamagnetism was observed in doped samples.•The transition temperature increases with the increase of doping concentration. Iron (Fe) doped ZnSe (ZnSe:Fe) microspheres with differen...
