​Magnetodielectric/ Pyroelectric current measurement Option for QD PPMS

PPMS copy.jpg



Using the versatile Quantum Design PPMS, CRYONANOs automated Magneto-dielectric Measurement Module Option  nhances the wide measurement capabilities of the PPMS to allow popular AC measurements such as dielectric constant, AC conductivity, Capacitance, Phase information, Nyquist Plots etc.  as a function of Magnetic Fields up to ± 16 tesla and standard temperature ranges of 1.9 – 400 K.  

The setup consists of an insert with low noise, guarded electrical  wiring connected   to   an inbuilt breakout box which in turn is  connected to an electronic   instrument panel.   The panel is controlled through software with the PC. The software controls the given experimental   scheme with magnetic field, temperature as well as frequency setting/sweeps by controlling the  Magnetic Field and Temperature controller of the PPMS.

Salient Features


Measurement at low temperature and under high magnetic field  with Guaranteed accuracy in the range from 1 mΩ to 200 MΩ  (depends on measurement configuration settings):  ΔZ = ±0.05 % Δθ = ±0.03 %.

Frequency range of measurement from 4 Hz to 2 MHz with minimum resolution of 10 mHz and fast  1ms acquisition speed

Built in Cryogenic Cable length Compensation.

Facility of in-plane and out-of-plane measurement with respect to   applied magnetic field.

Special PCB for quick sample change and thermalization.


Fully Automated user friendly Labview Software for Instrument Control and automation


What you get with this setup

  • Specially designed insert having BNC connectors and cryogenic coaxial wiring.

  • Impedance analyzer and interfacing hardware through Ethernet connector.

  • User friendly software for multiple parameter sweeps and data acquisition

  • Mini portable 19-inch rack mounting system

Multi-function probe


The setup comes with a multi-function probe option which allows the use of PPMS just as a cryostat with a magnetic field while making the electrical measurements from outside using a separate computer. The probe wiring is done using cryogenic co-axial cables with a breakout box at the top consisting of special BNC connectors with large isolation. This probe is used for direct access to the sample chamber puck connector provided by CRYONANO in this case. The signal accessed from the top goes into the measurement system kept in the instrument rack communicating to the PPMS through LAN.



The TABBED software provided with the system communicates with the PPMS MultiVu software for controlling its Temperature and Magnetic Field while measuring various parameters with the impedance analyzer in a larger phase space. This provides maximum automation while providing a powerful performance for such a complex measurement.

Measurements such as ε (B,T,f) or Z, ɸ (B,T,f) can be quickly measured using the TABBED program making it easy to use with live graphical display. The raw data files can later be processed in Origin / Matlab etc. 

UV Mask Aligner

Semi-Automatic UV Mask aligner for research and small scale fabrication. 


Photolithography and mask aligners are part of a process called nanofabrication. It is a process by which a series of thin layer of different materials can be patterned to a desired shape. Lithographic techniques have played a central role in the advancement of semiconductor process technologies. MODEL CN500 MASK ALIGNER developed by CRYONANO is a state of the art system developed with highest quality at extremely low cost. It is completely UV led based with automatic vacuum and Mask holding controls and automatic UV exposure units.
