Existence of ferromagnetism and structural characterization of nickel doped ZnO nanocrystals

► The DMS nanoparticles are prepared by microwave irradiated solvothermal process. ► The grain size estimation using transmission electron microscope is less than 20 nm. ► RTFM was confirmed in Zn0.9Ni0.1O combination. ► RTFM was induced by Ni ions, not for secondary phase or defects in the crystal.
