Quantum Design, Inc. VersaLab™ 3 Tesla Cryogen Free Vibrating Sample Magnetometer

Quantum Design introduces its first portable, cryogen-free cryocooler-based material characterization platform – VersaLab. With a temperature range of 50 – 400K, this 3 tesla platform is perfect for accomplishing many types of materials characterization in a limited space.

As with all Quantum Design instruments, VersaLab is a fully automated turnkey system with a user-friendly interface, and utilizes technology developed for Quantum Design’s popular Physical Property Measurement System (PPMS®). VersaLab is specifically designed for material characterization up to 3 tesla and over a wide temperature range without the need of liquid cryogens. Utilizing a new approach to cryocooler equipment design, VersaLab employs a new 4He-based temperature control system and gas flow technology that eliminates the need for liquid cryogens.

Integrated VersaLab Measurement Applications

PPMS Family Options Compatibility Table

  • Thermal Measurements

  • Magnetometry

  • Electro-Transport

  • High Pressure

Heat Capacity Option

  • Completely automated relaxation technique from 50 - 400 K
  • Integrated data acquisition electronics and analysis software

Thermal Transport Option

AC Resistivity ρ

  • Measured by using precision DSP current source and phase-sensitive voltage detection.

Thermal Conductivity κ

  • Measured by applying heat from the heater shoe in order to create a user-specified temperature differential between the two thermometer shoes.

Seebeck Coefficient α

  • Measured by creating a specified temperature drop between the two thermometer shoes - just as it does to measure thermal conductivity. However, for Seebeck coefficient the voltage drop created between the thermometer shoes is also monitored.

Thermoelectric Figure of Merit ZT

  • Determined here simply as the algebraic combination α2T /(κρ) of the three measured quantities - thermal conductivity, Seebeck coefficient, and AC electrical resistivity.
