热膨胀和磁致伸缩，即材料对温度和磁场的应变响应，特别是低温下的性质，对于研究低温工程和材料科学中的电子和声子性质、相变、量子临界性和其他有趣的现象非常有用。然而，传统的膨胀计不能轻易地提供磁场和超低温(<；77K)环境。本文描述了基于物理性能测量系统(PPMS)的应变片方法在低温下的热膨胀和磁致伸缩的设计和测试结果。用LabVIEW开发了接口软件和自动化程序。样品温度范围可在1.8~400K范围内连续可调。利用该PPMS辅助测量系统，我们可以方便、准确地观察不同固体材料的线性热膨胀随温度和磁场的变化。
Thermal expansion and magnetostriction, the strain responses of a material to temperature and a magnetic field, especially properties at low temperature, are extremely useful to study electronic and phononic properties, phase transitions, quantum criticality, and other interesting phenomena in cryogenic engineering and materials science. However, traditional dilatometers cannot provide magnetic field and ultra-low temperature (<77 K) environment easily. This paper describes the design and test results of thermal expansion and magnetostriction at cryogenic temperature using the strain gauge method based on a Physical Properties Measurements System (PPMS). The interfacing software and automation were developed using LabVIEW. The sample temperature range can be tuned continuously between 1.8 and 400 K. With this PPMS-aided measuring system, we can observe temperature and magnetic field dependence of the linear thermal expansion of different solid materials easily and accurately.
