PPMS- Phys. Property Measurement System PPMS-9 + EverCool-II.  


The Quantum Design PPMS represents a unique concept in laboratory equipment: an open architecture, variable temperature-field system, designed to perform a variety of automated measurements. Use the PPMS with our specially-designed measurement options, or easily adapt it to your own experiments. Sample environment controls with fields ± 9 tesla and temperature range of 1.9 - 1000 K.

3.      Magnetometry 


·       VSM 

The vibrating sample magnetometer (VSM) is a power- ful measurement system to be used for magnetic sample characterization. The VSM option transforms your PPMS into a sensitive DC magnetometer for fast data acquisition. The movement of the sample is done by a special sample transport, which has a linear character- istic and thus is very precise and flexible. The optional oven and large bore upgrade are useful and further extend the capability of the VSM.

 ·       The AC measurement system (ACMS) provides you with the capability to perform both AC susceptibility and extraction DC magnetization measurements without changing hardware.

 Temperature range - 1.9 - 350 K 

AC frequency range - 10 Hz to 10 kHz

AC field amplitude range - 2 mOe to 15 Oe

AC susceptibility sensitivity - 2 x 10–8 emu at 10 kHz

DC sensitivity - 2.5 x 10-5 emu to 5 emu

4.      Electro transport 

 ·       DC resistivity 

Current range - 5 nA to 5 mA

Sensitivity - 20 nV

·       AC transport measurement system (ACT) 

The AC transport measurement system (ACT) option is a precision current source and voltage detector that supports four different types of automated, electrical transport measurements: AC resistivity, five-wire Hall effect, I-V curve, and critical current. A PPMS with integrated ACT provides fast data acquisition and the convenience of measuring up to two samples on a single sample mount.

 Current range - 10 μA to 2 A

Current range: sensitivity - 1 nV @ 1 kHz

Frequency range - 1 Hz to 1 kHz

 ·       Electro-transport option (ETO) 

 The electro-transport option (ETO) enables users to make several different types of electric transport mea- surements over a wide range of resistance values and sample types. It includes the measurement of AC and DC resistance, I-V curves, and differential resistance.
