Free-Cryogen Physical Property Measurement System

The free-cryogen physical property measurement system (PPMS) which is supported by NSF-MRI program (NSF Award: DMR 0821284). This system includes capabilities for measuring electrical conductivity, magnetoresistance, Hall effect, DC and AC susceptibility, and heat capacity. The cryogen-free cryocooler-based system allows measurements from 1.6 to 325 K. The 9 Tesla field will be a unique feature of this system. These are physical property measurements and materials characterizations which are relevant to most fields in physics, and materials science and engineering. This cryogen-free system will incur low operating costs in low temperature measurements.
