Lateral compositionally-graded thin films are powerful media for the observation of phase boundaries aswell as for high-throughputmaterials exploration. We herein propose amethod to prepare epitaxial lateral compositionally-graded films using a dual-beampulsed laser deposition (PLD)method with two targets separated by a partition. [...]

We study the interplay between epitaxial strain, film thickness, and electric field in the creation, modification, and design of distinct ferroelastic structures in PbTiO thin films. Strain and thickness greatly affect the structures formed, providing a two-variable parameterization of the resulting self-assembly. [...]

The origin of "giant" flexoelectricity, orders of magnitude larger than theoretically predicted, yet frequently observed, is under intense scrutiny. There is mounting evidence correlating giant flexoelectriclike effects with parasitic piezoelectricity, but it is not clear how piezoelectricity (polarization generated by strain) manages to imitate flexoelectricity (polarization generated by strain gradient) in typical beam-bending experiments, since in a bent beam the net strain is zero.

One of the main strategies to control magnetism by voltage is the use of magnetostrictive-piezoelectric hybrid materials, such as ferromagnetic-ferroelectric heterostructures. When such heterostructures are subjected to an electric field, piezostrain-mediated effects, electronic charging, and voltage-driven oxygen migration (magnetoionics) may simultaneously occur, making the interpretation of the magnetoelectric effects not straightforward and often leading to misconceptions.

La flexoelectricidad es la capacidad de los materiales para generar electricidad al deformarse de forma no homogénea. Es una propiedad de todos los materiales y, en principio, posible que existiera en biomateriales. [...]
Flexoelectricity is the ability of materials to generate electricity upon being bent, or, more generally, upon being inhomogeneously deformed. It is a property that is allowed by symmetry in all materials and, therefore, it was in principle possible that it existed in biomaterials -one precedent existed for their observation in inner-ear stereocilia, in fact, pointing to its importance for acousto-electric transduction in mammalian hearing.
