The 11th APCTP Workshop on Multiferroics

In the push for the exploration of emergent materials, the ministry of science and technology (MOST) of Taiwan has founded a program called "Taiwan Consortium of Emergent Crystalline Materials (TCECM)" since 2009. As a key laboratory of this program, the goal of Atomic Foundry of Complex Oxides is to develop new functional oxide materials by atomic engineering. Currently it serves as a platform to connect the related researchers domestically and internationally. In order to promote the performance and visibility of this platform, Taiwan Oxide Forum was held since 2016. This year we would like to invite researchers who are interested in the research field of multiferroics to join us to share your results and to exchange ideas. We believe such an activity can team up more people in this research field to make more contribution to next-generation technology.

Multiferroics are materials that display spontaneous ferroelectric and magnetic ordering at the same time, while the cross-coupling between the magnetism and ferroelectricity in multiferroics represents the core issue of the physics of multiferroics. This coupling allows substantially intriguing physical phenomena and magnetoelectric functionalities which can potentially be exploited not only in the construction of novel and multifunctional spintronic devices. Such materials have attracted considerable attention, from the viewpoints of both fundamental science and practical applications in the electronics industry. In particular, the so-called electrically controlled magnetism e.g., fine control of magnetic memory by an electric field with ultra-low energy consumption and high efficiency is being highly appealed.

The field of multiferroic physics and materials has become one of the most rapidly developing activities in condensed matter research in the past more than ten years. The compatibility between ferroelectricity and magnetism, the multiferroic domain engineering, the electromagnon excitation and manipulation, and the artificial multiferroic heterostructures etc. are several hot topics among the multiferroic researches in recent few years. Along these lines, nevertheless, useful applications of multiferroics require that both magnetoelectric coupling is significant and the ordering temperatures are high. To date, the known multiferroics either show rather reduced coupling, or have low ordering temperatures with small values of ordered moments. While advances have been made in making new compounds, characterization, theoretical modeling and understanding of the underlying physical mechanisms, the complete understanding is yet to be achieved, and the ultimate goal of room temperature multiferroics with strong magnetoelectric coupling remains to be materialized. A workshop dedicated to the topic of multiferroics is therefore highly desirable and timely. That is the reason why we focus on multiferroics this year.
