Abstract

AbstractThis chapter begins with some physical concepts and basic technologies related to information storage, including the concepts of magnetism and ferroelectricity, as well as magnetic and ferroelectric storage technologies. By comparing and summarizing the aforementioned information storage technologies, new requirements and challenges for the current information storage technology have been put forward and the phenomena, as well as the concepts of multiferroic materials and magnetoelectric coupling effects have been introduced. Then the research progresses about multiferroic materials/structures and magnetoelectric coupling effects have been reviewed, including some representative work in the compounded multiferroic structures and electric-field control of magnetization. Finally, the prospective applications of multiferroic materials in the information storage have been addressed, and the pioneer works regarding the multiferroic/magnetoelectric memories and electric-writing/magnetic-reading spintronic devices have also been introduced.KeywordsExternal Electric FieldFerroelectric MaterialMultiferroic MaterialElectrical ControlFerroelectric OrderThese keywords were added by machine and not by the authors. This process is experimental and the keywords may be updated as the learning algorithm improves.
