Physical Properties Measurement System (PPMS)

我们申请了一种多功能测量站，用于表征物理材料特性(物理特性测量系统：PPMS)，如比热、导电性、磁阻和磁化率。由于该系统的工作磁场高达14特斯拉，涵盖低温和高温范围(2K&lt；T&lt；1000K)，因此可以在非常宽的参数范围内测量材料。这对于制备具有特殊电磁性能的新型功能材料和量子材料至关重要。这一通用测量系统还使晶体的基本表征成为所有进一步电子、光学和磁性光谱研究的先决条件。由于操作简单，一方面自动测量站可以被不同的群体独立使用；另一方面，它的巨大变化性允许它针对非常特殊的个人用户问题进行适配和扩展。斯图加特大学的所有成员都可以通过AMICA核心设施使用该测量系统。

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.
