设备简介

主要功能："PPMS系统是在一个控制的低温和强磁场平台上，集成全自动的磁学、电学、热学等各种物性测量手段。这样的设计使得整个系统的低温和强磁场环境得到了充分的利用；一个PPMS系统由基本系统和各种测量和拓展功能选件构成：基本系统提供低温和强磁场的环境，以及整个系统的软硬件控制中心；用户在基本系统平台的基础上选择自己感兴趣的各种测量选件和拓展功能选件。对于绝大多数常规实验项目，PPMS已经设计好了全自动的测量软件，和具有标准测量功能的硬件，如交直流电阻率、磁电阻、微分电阻、霍尔系数、伏安特性、磁滞回线、热磁曲线、比热等等。 PPMS system is a controlled low temperature and high magnetic field platform, the integration of automatic magnetic, electrical, thermal and other physical property measurement means. This design makes full use of the low temperature and strong magnetic field environment of the whole system; A PPMS system consists of the basic system and a variety of measurement and extension function options: the basic system provides a low temperature and high magnetic field environment, and the software and hardware control center of the whole system; On the basis of the basic system platform, users can select various measurement options and extended function options that they are interested in. For the vast majority of conventional experimental projects, PPMS has designed fully automated measurement software and hardware with standard measurement functions, such as AC-DC resistivity, magnetoresistance, differential resistance, Hall coefficient, voltammetry characteristics, hysteresis loops, thermomagnetic curves, specific heat, and so on."
