Magnetometry at Durham

Durham University is equipped with a Quantum Design Magnetic Property Measurement System 3 (MPMS3). This instrument enables highly sensitive magnetic measurements under variable conditions. The instrument is based on detection via a superconducting quantum interference device (SQUID) and a 7 T superconducting magnet, with a sample temperature range of 2 K to 400 K. The system uses an Evercool refrigeration system, which liquefies helium, minimising the usage of this resource.

Capabilities:

• a vibrating sample magnetometer measurement system to achieve <1x10^-8 emu sensitivity necessary for time-efficient measurements on low-moment systems;
• AC susceptibility option for dynamic measurements;
• sample rotation option for systematic measurements on single crystals and films;
• ultra-low field conditions: ± 0.05 G with a 7 T magnet.

Our system is available to Durham researchers and also to external users. Please contact Prof Tom Lancaster (tom.lancaster@durham.ac.uk) to discuss your requirements.
