This proposal aims for a magnetocryotstat system that allows us to perform characterization measurements of solid-state samples over a wide temperature and magnetic-field range. In order to cover the broad range of different material classes, which are studied by the various collaborative research projects in our institute we need a modular system that first of all offers a variety of basic sample characterization via electrical resistivity, magnetization, and heat capacity measurements. These tools are often needed as a quality and performance control of new samples or devices, but besides that also reveal whether, e.g., an intended systematic variation of material's properties or of device properties appears feasible. In addition, the system shall be used as magneto-cryogenic platform for the implementation of broadband spectroscopic measurements. These methods are adapted to the PPMS via dedicated insets and sample-holders featuring coaxial lines suited for microwave application, high voltages, or even optical fibers. Such measurements are more specialized and rely on home-made hardware and software attached to the commercial system.

该提案的目的是磁cryotstat系统，使我们能够在很宽的温度和磁场范围内进行固态样品的表征测量。为了涵盖我们研究所各种合作研究项目所研究的各种不同材料类别，我们需要一个模块化系统，首先通过电阻率，磁化强度和热容测量提供各种基本样品表征。这些工具通常需要作为新样品或设备的质量和性能控制，但除此之外，还可以揭示，例如，材料性质或装置性质的预期系统变化似乎是可行的。此外，该系统应用作磁低温平台，用于实施宽带光谱测量。这些方法适用于PPMS，通过专用的插入物和样品架，其特点是适合微波应用、高压甚至光纤的同轴线。这种测量更加专业化，依赖于与商业系统相连的自制硬件和软件。
