如题，本项目导师是六大的，合作导师是巴黎南大的（也就是我导师）。有兴趣的可以联系 Vita Ilakovac：vita.ilakovac-casses@upmc.fr （导师） Pascale Foury-Leylekian：pascale.foury@universite-paris-saclay.fr （合作导师） 六大的老师我不太清楚，但是我导师人很好，实验室实力雄厚。这边合作导师不是大老板和小老板的关系，每个导师都会在你身上花同等的时间。 以下是研究基本信息 Title of the research project: Structure and elemental excitations in multiferoïc organic and metal-organic frameworks Thesis supervisor: Vita Ilakovac, Laboratoire de Chimie Physique - Matière et Rayonnement, Sorbonne University, Paris, France Co-director Pascale Foury-Leylekian, Laboratoire de Physique des Solides, Université ParisSaclay, Orsay, France Abstract Even if the ferroelectricity and the magnetic order usually appear separately, there are rare compounds, known as multiferroïcs, where the spin and the charge ordering coexist, and sometimes induce each other. The mechanism of their coexistence is one of major questions in today’s materials science. In the case of large magnetoelectric coupling, important applications of these materials can be found in data storage domain, as they offer the possibility to control ferroelectric properties by magnetic fields and magnetism by electric fields. Moreover, they are important for the development of sustainable energy sources, like solar cells, as they offer the possibility of efficient ferroelectric polarization-driven carrier separation. The object of the proposed work is to reach a better understanding of the conditions which are necessary to obtain a simultaneous appearance of the magnetic and the charge ordering. The systems we will be interested in are the organic charge-transfer salts, kappa-(BEDT-TTF)2X, and metal-organic perovskite-like framework [(CH)3NH2]Fe(HCOO)3. We will study their detailed structure and the elemental excitations, like dd-, charge transfer, or collective magnetic and phonon excitations. Two experimental techniques will mainly be used: diffraction (X-ray or neutron) and Resonant Inelastic X-ray Scattering (RIXS). The interpretation of the experimental data will be supported by ab-initio state-of-the-art electronic structure calculations and simulations of the experimental spectra. 有完整版的PDF，有兴趣的同学可以看看。 链接：https://pan.baidu.com/s/1yZsGg_b2GX7GWi7b4LGqwg 提取码：h5s5 |
