Abstract

In solid state systems, magnetism and polarity are two fundamental physical properties. Magnetoelectric coupling implies the manipulation of magnetism by electric field or control of polarity using magnetic field. It is significant for fundamental sciences and has broad application prospects [1]. However, under most circumstances, efficient magnetoelectric coupling turns out to be challenging due to the mutual exclusion between magnetism and polarity [2]. In this talk, I will introduce our recent progress in overcoming these obstacles. We have proposed some new concepts of magnetoelectricity and demonstrated possible strategies to realize strong intrinsic magnetoelectric coupling in unconventional ways [3, 4].
