We are a research group focusing on experimental studies of ferroic materials and related phenomena. Particularly, we are interested in exotic physics in van der Waals ferroic crystals，including but not limited to ferroelectric, ferromagnetic, ferroelastic, multiferroic order parameters and their coupling effects with various energy fields (mechanical, light, electric, magnetic, thermal, etc.).
本课题组主要从事铁性有序材料和相关物理现象的实验研究工作。主要的研究兴趣集中在范德华铁性晶体的奇异物理性质上，包括铁电性、铁磁性、铁弹性、多铁性以及这些序参量和不同能量场（力、光、电、磁、热等）的耦合效应。
