Query: Magnetic orders of LaTiO$_3$ under epitaxial strain: a first-principles
  study   Perovskite LaTiO$_3$ bulk is a typical Mott-insulator with G-type
antiferromagnetic order. In this work, the biaxial strain effects on the ground
magnetic order of LaTiO$_3$ films grown on various substrates have been
studied. For the compressive strain, LaTiO$_3$ films grown on LaAlO$_3$,
LaGaO$_3$, and SrTiO$_3$ substrates undergo a phase transition from the
original G-type antiferromagnet to A-type antiferromagnet. The underlying
physical mechanisms are the lattice distortions tunned by strain. While for the
tensile strain, the BaTiO$_3$ and LaScO$_3$ substrates have been tested, which
show a tendency to transit the LaTiO$_3$ to the C-type antiferromagnet.
Furthermore, our calculations find that the magnetic transitions under
epitaxial strain do not change the insulating fact of LaTiO$_3$.
