We apply for a versatile measuring station for the characterization of physical material properties (Physical Properties Measurement System: PPMS), such as specific heat, electrical conductivity, magnetoresistance and magnetic susceptibility. Since the system operates with a magnetic field of up to 14 Tesla and covers both the low and high temperature range (2 K < T < 1000 K), materials can be measured over a very wide parameter range. This is crucial for the fabrication of new functional and quantum materials with special electronic and magnetic properties. This universal measurement system also enables the basic characterization of crystals as a prerequisite for all further spectroscopic investigations of electronic, optical and magnetic properties. Due to its simple operation, the automatic measuring station can be used independently by different groups on the one hand; on the other hand, its great variability allows it to be adapted and expanded for very special problems of individual users. The measuring system is available to all members of the University of Stuttgart via the AMICA Core Facility.

我们申请一个多功能测量站，用于表征物理材料的性能（物理性能测量系统：PPMS），如比热，电导率，磁电阻和磁化率。由于该系统在高达14特斯拉的磁场下工作，并且覆盖低温和高温范围（2k < T < 1000k），因此可以在非常宽的参数范围内测量材料。这对于制造具有特殊电子和磁性质的新型功能和量子材料至关重要。这种通用测量系统也使晶体的基本表征成为电子、光学和磁性的所有进一步光谱研究的先决条件。由于其操作简单，自动测量站一方面可以由不同的组独立使用；另一方面，它的巨大可变性使它能够适应和扩展到个人用户的非常特殊的问题。测量系统可通过AMICA核心设施提供给斯图加特大学的所有成员。
