7. Objective of Seminar This seminar covers novel materials and properties of strongly correlated electron systems including exotic superconductor, multiferroics, oxide interfaces, novel spectroscopy, and so on. The main purpose of this seminar is to provide a forum for the discussion of the latest progresses on a broad range of the above-mentioned topics. This seminar also aims to promote the exchange and collaboration of researchers in the field among Asian countries, especially, Japan and Korea, and to contribute to the development of materials science and condensed matter physics. This seminar also encourages participations by young researchers and students, and provides the opportunity for the international exchange among young researchers and students.
