Science and Technology of Complex Correlated Oxides: The Legacy of John Goodenough

Abstract

Summary. Its an absolute pleasure to be able to write this article to honor Professor John Goodenough on his 100th birthday. John, here is wishing you many more years of wonderful science with mirth and laughter! I have had the pleasure of knowing John for more than two decades and also following in his footsteps (albeit at a great distance from him), working on complex correlated oxides for my entire professional career, starting from the Hi-TC cuprates, manganites that display colossal magnetoresistance, ferroelectricity and most recently looking at the coupling between electricity and magnetism in multiferroics as well as the intricacies of spin transport in correlated oxides. This article is written on behalf of many colleagues, collaborators, and researchers in the field of complex oxides as well as current and former students and postdocs who continue to enable and undertake cutting-edge research in the field of multiferroics, magnetoelectrics, and broadly correlated electron materials physics as well as the pursuit of electric-field control of magnetism. What I present is something that is extremely exciting from both a fundamental science and applications perspective and has the potential to revolutionize the field of microelectronics. To realize this potential will require numerous new innovations, both in the fundamental science arena as well as translating these scientific discoveries into real applications. Thus, this article attempts to bridge the gap between fundamental materials physics and the actual manifestations of the physical concepts into real-life applications, a spirit that John’s entire career has embraced.
