Ferroelectric atomic displacement in multiferroic tetragonal perovskite Sr${}_{1/2}$Ba${}_{1/2}$MnO${}_3$

D. Okuyama, K. Yamauchi, H. Sakai +5

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${}^{-3}$ Angstrom for an atomic displacem…
