Integrated Physical Property Measurement System PPMS

Integrated Physical Property Measurement System PPMS
Physical Property Measurement System (PPMS) ®)
The design concept of PPMS system is to integrate fully automatic magnetic, electrical, thermal, morphological, ferroelectric, and dielectric properties measurement methods on a finely controlled low-temperature and strong magnetic field platform. This design makes full use of the low temperature and strong magnetic field environment of the entire system, greatly reducing the cost of purchasing instruments for customers, avoiding the cumbersome and error of building their own experiments, and can quickly realize the valuable research ideas of researchers.
A PPMS system consists of a basic system and various measurement and expansion function options: the basic system provides a low-temperature and strong magnetic field environment, as well as the software and hardware control center of the entire system; On the basis of the basic system platform, users can choose various measurement options and expansion 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, volt ampere characteristics, critical current, AC magnetization, hysteresis loop, thermal magnetic curve, specific heat, thermoelectric effect, Seebeck coefficient, thermal conductivity, and morphology characterization, etc. The reliability and convenience of these measurement methods have been recognized by the world scientific community in the past decade. Through unique and clever design, various measurement options on the PPMS system can be switched between each other easily and quickly without interference.
