The films were coherently grown at a temperature of 500\u00b0C for 2 hours. The magnetoelectric coefficient measurement was performed to show magnetoelectric coupling behavior of such heterostructures. The bottom BFO layer in the heterostructure was able to promote the grain growth of the LFO during the annealing process resulting in huge crystal size. These show the coexistence of ferroelectricity and magnetism, possess high dielectric constant and exhibit magnetoelectric coupling at room temperature. Improvement of the P\u2013E hysteresis loop was observed for the heterostructure due the decrease of leakage current caused by the LFO sublayer. Room temperature magnetic coercive field measurements indicate that the LFO and LFO\/BFO present different magnetic behavior which is influenced by the crystallite size. Such materials may be of great significance in basic as well as applied research.<\/p>\n<div class=\"responsive-embed\"><iframe loading=\"lazy\" title=\"I SPIMF - Alexandre Zirpoli Sim\u00f5es\" width=\"1168\" height=\"657\" src=\"https:\/\/www.youtube.com\/embed\/Zr5A4KqxXBw?feature=oembed\" frameborder=\"0\" allow=\"accelerometer; autoplay; encrypted-media; gyroscope; picture-in-picture\" allowfullscreen><\/iframe><\/div>\n","protected":false},"excerpt":{"rendered":"<p>Alexandre Zirpoli Sim\u00f5es Universidade Estadual Paulista Abstract- BiFeO 3 (BFO) and LaFeO 3 (LFO) heterostructures were obtained at room temperature on Pt\/TiO 2 \/SiO 2&hellip;<\/p>\n<p><a href=\"http:\/\/cdmf.org.br\/spimf2019\/new-approaches-towards-artificial-multiferroics\/\" class=\"read-more-link\"><span class=\"read-more-icon\"><\/span>Leia mais<\/a><\/p>\n","protected":false},"author":1,"featured_media":1353,"comment_status":"closed","ping_status":"open","sticky":false,"template":"","format":"video","meta":{"_exactmetrics_skip_tracking":false,"_exactmetrics_sitenote_active":false,"_exactmetrics_sitenote_note":"","_exactmetrics_sitenote_category":0,"footnotes":""},"categories":[27],"tags":[],"class_list":["post-937","post","type-post","status-publish","format-video","has-post-thumbnail","hentry","category-palestras","post_format-post-format-video"],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v24.2 -
