On ``Epitaxial Pb(Zr,Ti)O$_3$ thin films with coexisting tetragonal and rhombohedral phases''

2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/18603I present here theory of PZT thin film - MgO substrate system thermal expansion effect. I show that elastic properties of the substrate have to be taken into account to describe this effect.2 pages, 1 figure, Comment on S. H. Oh and H. M. Jang, Phys. Rev.
