VersaLab is the first cryogen-free Vibrating Sample
Magnetometer (VSM) from Quantum Design. Due to its
compact size it is a mobile device. The sensitivity of this
3 Tesla VSM is 10-6 emu/ Hz.
As with all Quantum Design measurement instruments,
VersaLab is a fully automated turnkey system with a
user-friendly interface. It is specially designed for magnetic material characterization over a wide temperature
range. Since it includes a cryocooler there is no need
for any cryogenic liquid. The VersaLab utilizes the technology from Quantum Design‘s popular PPMS (Physical
Property Measurement System)
VersaLab gives the user
