Cryogen-free dilution refrigerator has 12T magnet

Oxford Instruments has launched an integrated cryogen-free dilution refrigerator with a 12T superconducting magnet.

The system operates without liquid helium and only uses a single pulse tube refrigerator.

It offers the ability to control temperatures from below 10mK to 30K and magnetic fields up to 12T on the same instrument without any external manipulation of the sample environment.

This is suitable for applications such as neutron scattering, where sample alignment is paramount.

Having a single piece of equipment saves experimental space and time and will bring new research capabilities, the company said.

For many families of novel materials, tracking phenomena such as spin ordering and antiferromagnetism over wide temperature ranges in a magnetic field is key to understanding their intrinsic behaviour.

Oxford Instruments said this tool holds great promise for the development of future new materials.
