The drive to miniaturization has induced a high interest in the preparation and investigation of molecule-based compounds. In the frame of this project versatile spectroscopic techniques like X-ray photoelectron spectroscopy (XPS), X-ray absorption/emission spectroscopy (XAS/XES) and X-ray magnetic circular dichroism (XMCD) are to be employed for investigations of molecule-based magnetic solids. We will experimentally probe element-specific occupied and unoccupied states in the valence band region as well as deep-core states whose spectral features reflect magnetic properties. Together with an appropriate computational approach, we expect to establish a clear correlation between the electronic structure and magnetic properties. The goal of this project is to deduce relevant properties which govern the exchange interaction between magnetic orbitals in metal-organic compounds.

小型化的推动引起了人们对基于分子的化合物的制备和研究的高度兴趣。在该项目的框架中，X射线光电子能谱（XPS）、X射线吸收/发射光谱（XAS/XES）和X射线磁圆二色性（XMCD）等通用光谱技术将用于研究基于分子的磁性固体。我们将通过实验探测价带区域中元素特定的占据和未占据状态以及其光谱特征反映磁性的深核状态。结合适当的计算方法，我们期望在电子结构和磁特性之间建立明确的相关性。该项目的目标是推断控制金属有机化合物中磁轨道之间交换相互作用的相关特性。
