Electronic and Magnetic Properties of Complex Metallic Alloys

该提案是Paketantrag“复杂金属合金的物理特性”的一部分，该提案与EC卓越网络“复杂金属合金”密切相关。复杂金属合金（CMA）具有独特的结构特征，这些结构特征直接决定了各种物理性能。特别是，簇子结构对电子、磁性和热性质具有相当大的影响，并且导致例如负的电导率温度系数，尽管材料仅包含金属元素。我们将描述各种CMA的电子，磁性和热特性，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材料具有不寻常的薄膜性质，特别是如果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相的薄膜，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.
