Ferroelectric atomic displacement in multiferroic tetragonal perovskite Sr_{1/2}Ba_{1/2}MnO_{3}
We investigate the crystal structure in multiferroic tetragonal perovskite Sr_{1/2}Ba_{1/2}MnO_{3} with high accuracy of the order of 10^{−3} Å for an atomic displacement. A large atomic displacement of the Mn ion from the centrosymmetric position, comparable with the off-centering distortion in the...
