A. ; Fontcuberta, J. ; Sánchez, F. ; Herranz, G. | American Physical Society | 2017-09-07Two basic lattice distortions permeate the structural phase diagram of oxide perovskites: antiferrodistortive (AFD) rotations and tilts of the oxygen octahedral network and polar ferroelectric modes. With some notable exceptions, these two order[...]texto impreso

Via x-ray linear dichroism spectroscopy, w[...]texto impreso
Scigaj, M. ; Dix, N. ; Cabero Piris, Mariona ; Rivera Calzada, Alberto Carlos ; Santamaría Sánchez-Barriga, Jacobo ; Fontcuberta, J. | Amer Inst Physics | 2014-06-23We show that yttria-stabilized zirconia (YSZ) films deposited on structurally dissimilar SrTiO_(3)(110) substrates exhibit two-dimensional layer-by-layer growth. We observed that, up to a thickness of about 15 nm, the square (001) basal plane of[...]
