Within this common project new metastable crystalline Chromium-Antimony compounds will be synthesized using various preparation techniques and characterized comprehensively concerning their crystallographic, electrical and magnetic properties. The elements will be deposited on an inert substrate either by the layer-by-layer or co-deposition method and brought to reaction by a well-defined temperature treatment. The reaction will be followed and studied in a temperature and time resolved way by in-situ X-ray diffraction and edge spectroscopy. This experimental work will be supported by corresponding theoretical investigations, using a broad spectrum of modern tools. This way the theoretical work should explain the special characteristics of the Cr-Sb phase diagram and give hints to the existence and the realizability of new metastable phases. Furthermore, they should allow for a detailed interpretation of the experimental results by calculating the various spectroscopic and physical properties.

在这一共同项目中，将使用各种制备技术合成新的亚稳定结晶铬-锑化合物，并对其结晶、电和磁性进行全面表征。这些元素将通过逐层或共沉积的方法沉积在惰性衬底上，并通过明确定义的温度处理进行反应。用原位X射线衍射法和边缘能谱对反应进行了跟踪和研究。这项实验工作将得到相应的理论研究的支持，使用广泛的现代工具。这样，理论工作就可以解释Cr-Sb相图的特殊特征，并对新的亚稳相的存在和实现提供线索。此外，它们应该允许通过计算各种光谱和物理性质来详细解释实验结果。
