Cryogenic Limited (United Kingdom) Physical Properties Measurement System (PPMS) Low Temperature Measurement System: T-1.4 K B-9T Physical Properties Measurement System (PPMS)
The PPMS system allows for the measurement of electrical (electrical conductivity, Hall effect, etc), and magnetic (DC magnetization and AC susceptibility) properties at magnetic fields up to an optional 7,9 or 16T (superconducting solenoid magnets), and accurately controlled temperatures in the range 1.9 < T < 400K. Temperatures up to 1000K can be obtained with an optional "oven" insert. The apparatus is PC controlled and is completely programmable (such that a prolonged sequence of measurements under varying temperature and field values or sweeps can be done). The PPMS is readily expandable, with a variety of specialist specimen stages and measurement options and very user friendly. It is supplied either in a conventional cryostat dewar, which is very economical in the use of liquid helium, or in a cryostat with built-in cryo-refrigerator (Evercool option).
