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.

单分子磁体被认为是一种很有前途的新型磁性数据存储材料。近年来，特别是以镧系离子为基础的稀土化合物已显示出巨大的前景和科学兴趣。迄今为止的进步都是基于意外发现。缺乏对其电子和磁性能及其与分子结构关系的深入研究。本项目详细研究了镧系单分子磁体的磁性能。特别是电子结构及其与磁性的关系将通过多技术实验和理论方法进行深入研究。此外，我们还与主要合作伙伴建立了合作关系，以便获得所有重要信息。该项目的结果将进一步了解镧系化合物在电子和几何结构方面对稳定磁化的要求。鉴于镧系元素在日常应用中日益重要，如磁铁和磁共振成像造影剂，了解镧系化合物的电子和磁性是必不可少的。最终，可以预见在新型磁性数据存储中的应用。
