“…Room temperature magnetic properties of TM-doped ZnO have been studied widely and in Table 4 a few recent findings are compiled which also convey the fact that observed RTFM is due to defect mediated exchange interactions. Fe-doped ZnO 91 and (Fe,Ni) co-doped ZnO 92 also exhibted FM ordering mediated through oxygen vacancies. Ali et al showed experimental and theoretical results emphasizing RTFM in Cu-doped ZnO due to the exchange interaction between Cu 2+ –Cu 2+ ions mediated by zinc vacancies.…”

“…A diluted magnetic semiconductor can be achieved through the incorporation of transition-metal (TM) elements including Ni, Cr, Co, Fe, and Mn into a non-magnetic semiconductor. DMS materials have inspired a great deal of academic and industrial research regarding their great potential in several fields, such as optoelectronics, sensors, light emitting diodes (LED), nanoelectronics, photonics, and spintronic devices [ 5 , 6 , 7 , 8 , 9 , 10 , 11 , 12 , 13 ]. Metal oxide semiconductors such as TiO 2 , SnO 2 , In 2 O 3 , and ZnO are known to exhibit DMS behavior as a result of TM-doping [ 14 , 15 , 16 , 17 , 18 , 19 , 20 , 21 , 22 , 23 ].…”

Undoped as well as (Co, Mn) co-doped Zinc oxides have been effectively developed on glass substrates, taking advantage of the spray pyrolysis procedure. The X-ray diffraction XRD as well as X-ray photoelectron spectroscopy (XPS) measurements have recognized a pure hexagonal wurtzite form of ZnO, and no other collateral phases such as MnO2 or CoO2 have been observed as a result of doping. The calculated values of the texture coefficient (TC) were between 0.15 and 5.14, indicating a dominant orientation along the (002) plane. The crystallite size (D) varies with the (Co, Mn) contents. The dislocation density (δ) as well as the residual microstrains increased after Co and Mn doping. Furthermore, the surface morphology of the films has been affected significantly by the Co and Mn incorporation, as shown by the scanning electron microscopy (SEM) investigation. The study of the optical properties exhibits a red shift of the band gap energy (Eg) with the (Co, Mn) co-doping. The magnetic measurements have shown that the undoped and (Co, Mn) co-doped ZnO thin films displayed room-temperature ferromagnetism (RTFM).
