Physical Properties Measurement System (PPMS)

我们申请了一个多功能测量站，用于表征材料的物理特性（物理特性测量系统：PPMS），如比热、电导率、磁阻和磁化率。 由于该系统可在高达14特斯拉的磁场下工作，并覆盖低温和高温范围（2 K < T < 1000 K），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的新型功能和量子材料至关重要。这一通用测量系统还可以对晶体进行基本表征，作为所有进一步光谱研究电子、光学和磁性的先决条件。由于其操作简单，一方面，自动测量站可以由不同的群体独立使用;另一方面，其巨大的可变性使其能够适应和扩展，以解决个别用户的特殊问题。该测量系统通过AMICA核心设施提供给斯图加特大学的所有成员。

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.
