Electronic and Magnetic Properties of Complex Metallic Alloys

该提案是Paketantrag“复杂金属合金的物理性质”的一部分，它与EC卓越“复杂金属合金”网络密切相关。复杂金属合金具有独特的结构特征，直接决定了其各种物理性能。特别是团簇子结构对电子、磁性和热性能有相当大的影响，并且例如导致电导率的负温度系数，尽管材料仅含有金属元素。我们将表征各种cma的电子、磁性和热性能，这些cma将具有不同程度的复杂性、结构和组成元素，由Paketantrag的合作伙伴生产。此外，作为大晶胞的直接结果，我们期望CMA材料具有不同寻常的薄膜特性，特别是如果薄膜厚度与晶格参数相当（或更小）。因此，我们计划生产选定的CMA相薄膜并研究其性能。

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.
