報告題目： Combining Light and Tips -- A Case Study of Electric and Magnetic Properties in Mixed-phase BiFeO3 報告人： Qing He Department of Physics, Durham University, Durham DH1 3LE, United Kingdom 報告時間： 2014-9-15 14:00 報告地點：清華大學物理系理科樓三樓報告廳摘要： In this talk, I will take tetragonal and rhombohedral mixed-phase BiFeO¬3 as an example to share with you about our investigating steps and thinking process when dealing with a new research problem. Ferroelectricity, magnetism and the electrical control of magnetization are of particular interest in emergent state of the material. In order to look deep into those properties, a combination of scanning probe microscopy (SPM) and x-ray absorption based techniques (including x-ray absorption spectroscopy (XAS), x-ray circular/linear dichroism (XCD/XLD) analysis, photo-emission electron microscopy (PEEM), etc.) has been employed. This talk will focus on the study process of how we first understand the ferroelectric and magnetic properties separately and then combining all the knowledge and tools to finally realise a deterministic electric control of magnetism in this system. 個人簡曆：何清，英國杜倫大學(Durham University)。2011年畢業于美國加州大學伯克利分校物理系，獲得物理博士學位。同年獲得美國勞倫斯國家實驗室(Lawrence Berkeley National Laboratory)ALS博士後基金(Advanced Light Source Postdoctoral Fellowship)的資助，開展博士後研究。2014年2月受聘于英國杜倫大學，任職講師，從事凝聚态實驗物理和材料科學的交叉領域研究,主要探索功能氧化物薄膜、界面、疇壁、表面以及納米結構等量子受限系統的新穎特性和物理機制。迄今為止已在國外重要學術期刊發表SCI論文超過40餘篇，其中包括Science 1篇，Nature子刊8篇，以及Physical Review Letters 10篇，論文引用超過2300次，H因子20。她博士期間曾獲得Jackson C.
