The epitaxial strain effects on the magnetic ground state of YTiO3 films grown on LaAlO3 substrates have been studied using the first-principles density-functional theory. With the in-plane compressive strain induced by LaAlO3 (001) substrate, A-type antiferromagnetic order emerges against the original ferromagnetic order. This phase transition from ferromagnet to A-type antiferromagnet in YTiO3 film is robust since the energy gain is about 7.64 meV per formula unit despite the Hubbard interaction and modest lattice changes, even though the A-type antiferromagnetic order does not exist in any RTiO3 bulks.
