Effect of epitaxial strain on magnetism in GdTiO3. a Magnetic configuration energy differences relative to the FM state. Again, positive energy differences indicate that the FM state is more stable than a particular AFM phase. Negative strains correspond to the compressive region, whereas positive strains are tensile. b In-plane (J ab ) and out-of-plane (J c ) Heisenberg exchange parameters (J > 0 corresponds to FM order) and c Weiss mean field critical temperature as a function of in-plane strain
