Fe, Co and Co[sbnd]Fe doped SnO2 thin films were deposited onto glass, indium tin oxide-coated glass, and Si substrates to investigate the influence of substrate material on the surface and magnetic properties. The motivation of this study is to investigate the magnetic, surface, and optical properties of doped SnO2 semiconductor materials as they vary with different substrate materials. The film surfaces are smooth and compact. Additionally, nano particles were observed. Thin films of SnO2 doped with Fe, Co and Co[sbnd]Fe doped SnO2 have a Curie temperature. Magnetization–temperature and magnetization–temperature graphs have shown the predicted magnetic properties. These films have giant magnetization and soft magnetic properties. In separately doped Fe and Co – SnO2 thin films, the M (emu) values are nearly the same. In Co and Fe-doped SnO2 thin films, the M (emu) values for the film deposited onto ITO-coated glass and uncoated glass are nearly the same.
