The aim of the project is to investigate the fundamental static and dynamic electronic and magnetic properties of individual molecular magnetic systems on surfaces. In particular the spin-dependent electron transport through these structures will be studied on the atomic scale and under well defined conditions. We belief, this unexplored area can be accessed nowadays with the new generations of scanning tunneling microscopes working at low temperatures and under high magnetic fields. The main advantage of molecular magnetic entities compared to conventional magnetic nanosystems is their almost unlimited potential to tune magnetic properties of metal centers and organic surroundings due to the possibilities offered by supramolecular chemistry. We want to first investigate magnetic centers in relatively simple systems of metal-organic networks and than address the more complex structures of molecular nanomagnets. The final goal of the suggested project is the controlled addressing and manipulation of magnetic and electronic properties of individual magnetic centers embedded in an organic environment. In addition to fundamental findings, our results will provide information necessary for nowadays frequently discussed possible applications of molecular nanomagnets, e.g. spintronic devices and quantum computing.

该项目的目的是研究表面上单个分子磁性系统的基本静态和动态电子和磁性。特别是通过这些结构的自旋相关的电子输运将在原子尺度上和定义良好的条件下进行研究。我们相信，随着新一代扫描隧道显微镜在低温和高磁场下工作，这一未开发的领域可以进入。与传统的磁性纳米系统相比，分子磁性实体的主要优点是由于超分子化学提供的可能性，它们几乎具有无限的潜力来调节金属中心和有机环境的磁性。我们希望首先研究相对简单的金属有机网络系统中的磁性中心，然后解决分子纳米磁体的更复杂结构。建议项目的最终目标是控制寻址和操纵嵌入有机环境中的单个磁性中心的磁性和电子特性。除了基本的发现，我们的研究结果将提供必要的信息，现在经常讨论的可能的应用分子纳米磁体，例如自旋电子器件和量子计算。
