N2 - The Mn-doped PbPdO2 nanograin film with many Pb vacancies was synthesized by using a sol-gel spin-coating method. The valence states for Pb, Pd and Mn ions were found to be 2 +, 2 + and the mixed one of 3 + and 4 +, respectively. The existence of Pb vacancies was believed to result in the increase of the Mn valence. The ferromagnetism and the antiferromagnetism were found to coexist in the formed Mn-doped PbPdO2 nanograin film. The ferromagnetism which can be maintained to above the room temperature was proved to be intrinsic. The carrier-mediated mechanism bridged to bound magnetic polaron model was used to explain the coexistence of the antiferromagnetism and the ferromagnetism within the Mn-doped PbPdO2 film.
