Speech Title:
Inducing ferroic ordering in perovskite oxides through epitaxial strain: first- principles results
Abstract:
In this talk I will review our latest work predicting new phases of bismuth perovskite oxides that appear when films are grown under epitaxial strain. These predictions focus on the ferroelectric and ferromagnetic (or antiferromagnetic) orderings of the new phases. We review materials such as BiMnO3, which should become ferroelectric as the strain gets larger, and Bi2NiMnO6, which should be ferroelectric and ferromagnetic in the regime of large tensile strains.
Bio:
Dr. Oswaldo Dieguez received his PhD from University of Santiago de Compostela, Spain. After postdoctoral stays at Cambridge, Rutgers, and MIT he joined the Institute of Materials Science of Barcelona as a staff researcher. He moved to the Department of Materials Science and Engineering of Tel Aviv University in 2013, where he is a senior lecturer (assistant professor). His research involves studying the properties of materials by modelling the behavior of their electrons and nuclei with the help of computers, mainly using density-functional theory. Most of his recent work is in the field of ferroelectrics and multiferroics, both in the development of new methodology and in its application to these materials of technological interest.
