报告简介：Pressure is one of the independent thermodynamic parameters, and has played an important role in determining the state of materials like temperature and composition [1]. It can be effective in shortening atomic distance, enhancing orbital overlap, and consequently modifying crystalline structures and tuning interactions. Thus, people can realize novel states & synthesize new materials under high pressure. In this talk first I give a short description about the application of pressure in material science, and the research field of my group. Finally, I will give a detailed introduction about our recent works, including: 1) Synthesis of new transition metal oxidizes (PbFeO₃ and PbHg₃Ti₄O₁₂) and the discovery of ferroelectricity, charge ordering, spin reorientation properties [2, 3]; 2) High pressure growth single crystal of Kitaev-type quantum spin liquid RuBr₃ and physical properties characterization [4].
