We have fabricated high-quality epitaxial EuTiO3(100) films on SrTiO 3 substrates by pulsed laser deposition. In situ reflection high-energy electron diffraction (RHEED) monitoring revealed clear intensity oscillation, indicating layer-by-layer growth of EuTiO3. Furthermore, the obtained films had atomically flat surfaces with a step-terrace structure. From magnetization vs temperature measurements, we confirmed that the EuTiO 3 films have antiferromagnetic ordering with a Néel temperature of 3.7 K, and that they could be transformed to a ferromagnetic state by applying a magnetic field. We also found that the magnetic properties of the EuTiO3 films are sensitive to cell volume, as predicted by recent first-principles band calculations.
