Spectroscopic investigations of lanthanide-ion-based single molecule magnets

单分子磁体已被认为是新型磁数据存储材料的潜在候选者。近年来，尤其是基于镧系离子的研究显示出了巨大的前景和科学兴趣。到目前为止，进展都是建立在偶然的基础上的。目前还缺乏对其电磁性质及其与分子结构关系的深入研究。本项目对稀土基单分子磁体的磁性进行了详细的研究。特别是电子结构及其与磁性的关系，将采用多技术实验和理论相结合的方法深入研究。此外，我们还与主要合作伙伴建立了合作关系，以便能够访问所有重要信息。该项目的成果将进一步加深对稀土化合物的电子和几何结构方面的稳定磁化要求的理解。鉴于镧系元素在磁体和磁共振成像造影剂等日常应用中的重要性与日俱增，了解其电子和磁性是必不可少的。最终，在新型磁数据存储中的应用是可以预见的。

Single molecule magnets have been proposed as promising candidates for novel magnetic data storage materials. In recent years, especially those based on lanthanide ions have shown great promise and scientific interest. Progress has so far been based on serendipity. In depth investigations of the electronic and magnetic properties and their relation to the molecular structure are lacking. This project deals with the detailed investigation of the magnetic properties of lanthanide-based single molecule magnets. Especially the electronic structure and its relation to the magnetism will be investigated deeply by means of a multitechnique experimental and theoretical approach. In addition, we have established collaborations with key partners to have access to all essential information. The outcomes of this project will further the understanding of the requirements for a stable magnetization in terms of electronic and geometric structure of lanthanide compounds. Knowledge of the electronic and magnetic properties of lanthanide compounds is indispensable in view of the growing importance of lanthanides in everyday applications such as magnets and magnetic resonance imaging contrast agents. Eventually, application in novel magnetic data storage can be foreseen.
