摘要
•Gd-doped ZnO films were synthesized by sol–gel spin coating technique.•Anomalous Hall Effect signal reveals intrinsic ferromagnetism and existence spin polarization in Gd-doped ZnO films.•MFM qualitatively proves the existence of spin polarization in the Gd-doped ZnO films.•Optical band-gap results indicate the existence of strong spin-exchange interaction.
