Lattice relaxation and ferromagnetic character of (LaVO <sub>3</sub> ) <sub>m</sub> /SrVO <sub>3</sub> superlattices
The experimental observation that vanadate superlattices (LaVO3)m/SrVO3 show ferromagnetism up to room temperature [U.Lüders et al., Phys.Rev. B 80, 241102R (2009)] is investigated by means of density functional theory.First, the influence of the density functional on the electronic and magnetic structure of bulk LaVO3 is discussed.Second, the band structure of …
