This proposal is part of the Paketantrag “Physical Properties of Complex Metallic Alloys”, which is closely linked into the EC Network of Excellence “Complex Metallic Alloys”. Complex metallic alloys (CMAs) possess characteristic structural features, which directly determine various physical properties. In particular the cluster substructure has considerable influence on the electronic, magnetic and thermal properties, and leads, for example, to a negative temperature coefficient of the electrical conductivity although the materials contain only metallic elements. We will characterize the electronic, magnetic and thermal properties of various CMAs, which will with various degrees of complexity, structure, and constituting elements be produced by partners in the Paketantrag. Furthermore, as a direct consequence of the large unit cells, we expect unusual thin-film properties of CMA materials, in particular if the film thickness is comparable (or smaller) than the lattice parameters. We therefore plan to produce thin films of selected CMA phases and investigate their properties.

该提案是Paketantrag“复杂金属合金的物理特性”的一部分，该特性与“复杂金属合金”的EC网络紧密相关。复杂的金属合金（CMAS）潜在的特征结构特征，这些特征直接决定各种物理特性。尤其是簇子结构已考虑对电子，磁性和热性能的影响，例如，尽管材料仅包含金属元件，但导致电导率的负温度核心。我们将表征各种CMA的电子，磁性和热性能，这些特性将由Paketantrag中的合作伙伴产生不同程度的复杂性，结构和构成元素。此外，作为大型单元细胞的直接结果，我们期望CMA材料的异常薄膜特性，特别是如果膜厚度比晶格参数可比（或较小）。因此，我们计划生产所选CMA相的薄膜并研究其性质。
