A method for forming a doped PGO ferroelectric thin film, and related doped PGO thin film structures are described. The method comprising: forming either an electrically conductive or electrically insulating substrate; forming a doped PGO film overlying the substrate; annealing; crystallizing; and, forming a single-phase c-axis doped PGO thin film overlying the substrate, having a Curie temperature of greater than 200 degrees C. Forming a doped PGO film overlying the substrate includes depositing a doped precursor in the range between 0.1N and 0.5N, with a molecular formula of Pby-xMxGe3O11, where: M is a doping element; y=4.5 to 6; and, x=0.1 to 1. The element M can be Sn, Ba, Sr, Cd, Ca, Pr, Ho, La, Sb, Zr, or Sm.
