Abstract
We present magnetotransport evidence for antiferromagnetism in films of the electron-doped cuprates Pr2−xCexCuO4. Our results show clear signature of static or quasistatic antiferromagnetism up to optimal doping x=0.15, with a quantum phase transition close to x=0.16, and a coexistence of antiferromagnetism and superconductivity for 0.12⩽x⩽0.15.
