Ferroelectrics are materials that can maintain spontaneous and reversible electric polarization. Relaxor-ferroelectrics that exhibit high electrostriction are ideal candidates for ferroelectric layer constructs due to their large piezoelectricity. Although the properties of relaxor ferroelectrics are known, their mechanistic origins remain a mystery, giving rise to an enigmatic form of materials. In addition to that, thin films are ineffective from substrate clamping and can substantially reduce piezoelectric in-plane strains. In a new report now published in Science Advances, Shane Lindemann and a research team in materials science, and physics in the U.S. and Korea, displayed low-voltage magnetoelectric coupling in an all-thin-film heterostructure using anisotropic strains induced by the orientation of the material. The team used an ideal ferroelectric layer of Pb(Mg1\/3Nb2\/3)O3\u2013PbTiO3 abbreviated PMN-PT during this work and coupled it with ferromagnetic nickel overlayers to create membrane heterostructures with magnetization. Using scanning transmission electron microscopy and phase-field simulations, they clarified the membrane response to understand the microstructural behavior of PMN-PT thin films, to then employ them in piezo-driven magnetoelectric heterostructures.&#013;<br \/>\n&#013;<br \/>\n&#013;<br \/>\n Click here for original story, <a href=\"https:\/\/phys.org\/news\/2021-11-low-voltage-magnetoelectric-coupling-membrane-heterostructures.html\" target=\"_blank\" rel=\"nofollow noopener noreferrer\">Low-voltage magnetoelectric coupling in membrane heterostructures<\/a>&#013;<br \/>\n&#013;<br \/>\n&#013;<br \/>\nSource: Phys.org&#013;<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Strain-mediated magnetic coupling in ferroelectric and ferromagnetic heterostructures can offer a unique opportunity for scientific research in low-power multifunctional devices.
