We present magnetotransport evidence for antiferromagnetism in films of the
electron-doped cuprates Pr2−x​Cex​CuO4​. Our results show clear
signature of static antiferromagnetism up to optimal doping x=0.15, with a
quantum phase transition close to x=0.16, and a coexistence of static
antiferromagnetism and superconductivity for 0.12≤x≤0.15
