Our cryogenics Lab is co-run with Prof. Andrew Briggs and Dr. Natalia Ares, and includes:
- Four Oxford Instruments dilution refrigerators, working down to 10 mK (base temperature), each equipped with: 48 highly filtered DC lines for single-molecule measurements; 6 high-frequency lines working up to 22 GHz; a three-dimensional vector magnet in a 6/1/1 T configuration; a fast-entry sample-loading system that allows cooling the samples down within 8 hours.
These cryostats can currently measure:
- EPR at
- Torque magnetometry down to 500 mK and in a three-dimensional vector field.
- Strong coupling of microwave photons to molecular magnets, using three- and two-dimensional cavities that can operate in mangetic fields.
We also routinely use the magnetometry facilities available in Oxford, including SQUID systems down to 1.8 K and 60 kOe.
