Overview
The PPMS System-9 is an open architecture, variable temperature and field system designed to perform a variety of scripted and automated magnetic and physical property measurements.
Common Research Applications
Magnetic properties: magnetic DC and AC susceptibility, magnetometry
Thermal properties: heat capacity, thermal transport, cryo-FMR
Electric properties: DC and AC resistance, electro transport
Specifications
Capable of 24/7 continuous operation
Measurement temperature range of 1.8 to 400 K with measurement sweep rate of 0.01 to 10 K/min
Continuous Low-Temperature Control (CLTC) for precise and uninterrupted operation below 4.2 K
Applied field strength of ± 9 Tesla
Field uniformity of ± 0.01 % over 5.5 cm
Measurement Options
Heat Capacity
The Heat Capacity option for the PPMS will run fully automated relaxation heat capacity measurements under high-vacuum.
AC Susceptibility
The AC Measurement System (ACMS) option can perform both AC susceptibility and DC magnetisation measurements without changing between hardware. A single automated measurement system is capable of both.
AC frequencies from 10 Hz to 10 kHz and field amplitudes from 0.05 Oe to 15 Oe
AC susceptibility measurement sensitivity of 1 x 10-8 emu at 10 kHz
DC magnetisation measurement sensitivity of 5 x 10-6 emu

AC Transport
The AC Transport (ACT) option support four different automated electrical transport modes: AC resistivity, five-wire Hall effect, I-V curves and critical current measurements.
Two samples can be loaded simultaneously
Current range of 10 μA to 2 A
Sensitivity of 1 nV at 1 kHz
Operational frequency range of 1 Hz to 1 kHz
DC Resistivity
The DC Resistivity option adds resistance bridge capabilities to the instrument providing four independent channels for van der Pauw and four-wire resistance measurements.
Ferromagnetic Resonance
The Cryo-FMR probe enables measurement of the Ferromagnetic Resonance (FMR) response of a material at variable temperatures and sample orientations parallel or perpendicular to the DC field.
