easyLab® Mcell Ultra

SQUID magnetometers, Pmax = 20 GPa, Tmin = 4 K
  • Miniature diamond anvil cell specifically designed for commercial SQUID magnetometers
  • Typically, one can expect pressures of up to 20 GPa when using diamond anvils with culets of 0.50 mm
  • Special engineered easyLab® Mpress enables more accurate control and reproducibility of the in-situ pressure versus applied force
  • The complete solution: provides a convenient and trouble free way to study magnetic properties of superconducting and ferromagnetic materials under ultra high pressures
  • Includes interfacing components to Quantum Design’s MPMS, but can be used in any other SQUID magnetometer
  • The easyLab® Mcell Ultra can also be used with the Vibrating Sample Magnetometer option
  • Superior customer support: consumables and replacement parts are readily available. If required, installations and training can be provided. Support and guidance via video call is also possible

SKU: A15201

Diamond Anvil Cell for Quantum Design’s MPMS®

The miniature diamond anvil cell easyLab® Mcell Ultra builds on the success of the clamp cell easyLab® Mcell 10. However, in contrast to the Mcell 10, the Mcell Ultra enables measurements up to much higher pressures, above 15 GPa (150 kbar). Typically, one can expect pressures of up to 20 GPa when using diamond anvils with culets of 0.50 mm. This is the recommended smallest culet size for the Mcell Ultra. Beyond this limit, the lateral alignment of the anvils becomes difficult to achieve. Also, the very small sample size makes the magnetic signal difficult to pick up and to extract from the background signal of the cell.

The easyLab® Mcell Ultra has a diameter of 8.5 mm and a length of 35 mm and is designed to work in commercial superconducting quantum interference device (SQUID) magnetometers, in particular the QD MPMS®.

Indeed, the easyLab® Mcell Ultra is supplied as a complete package. It provides end-users with all the necessary primary components of the pressure cell as well as interfacing parts to the sample rod of the MPMS®.

What is the maximum pressure I can achieve with the Mcell Ultra and a given culet size?

Culet size (µm) 500 600 800 1000
Pmax (GPa) (*) 20 14 8 5

(*) The Pmax values are only indicative. The maximum pressure achievable with a DAC is influenced by many others experimental parameters, like the gasket characteristics (material, thickness and hole size) or the pressure transmitting medium.
