All doped nanocomposites crystallized in hexagonal wurtzite formation of ZnO. No alteration in the wurtzite structure, with no evidence of any segregated secondary phase(s) was detected with increasing doping concentrations. This result unambiguously verified the substitution of Zn2+ sites by Co2+ ions in the ZnO host lattice for different doping concentrations. Moreover, room temperature ferromagnetic behavior was observed in all doped nanocomposite samples in the reported work. Present study clearly shows that mechanical ball-milling is a facile, inexpensive, eco-friendly method to synthesize crystalline and magnetic Co doped ZnO nano composites for next generation spin-based devices.eninfo:eu-repo/semantics/openAccessComposite materialsNanostructured materialsCrystal structureMicrostructureEXAFSX-ray diffractionArticle4810.1016/j.colcom.2022.1006112-s2.0-85126837214Q1WOS:000792914900005Q1
