SpectromagPT
The new cryogen-free magneto-optical superconducting magnet system, spectromagPT, is a Cryofree® version of our popular Spectromag® cryostat for magneto-optical studies is now available. It is a superconducting split pair, horizontal field magnet systems providing optical access to a sample in a variable magnetic field/low temperature environment.
- Magnetic fields up to 7 T. 10 T option available on request.
- 1.5 K to 300 K
- No gas flow over sensitive samples: the system uses a static exchange gas around the sample, preventing flow induced movement of delicate samples or measurements probes
- Quick sample change via top-loading probe. The sample can be changed while the system is cold. No need for
complicated load-lock mechanism and reloading into the gas
- No contamination or blockages: using a sealed circulation loop separate to the sample exchange gas. This also
increases the continuous running period of this system
- Excellent optical access in the horizontal plane both parallel and perpendicular to the field
