Torque magnetometry at Physics and Astronomy, University of Exeter

A cantilever torque magnetometer is used to investigate magnetic anisotropy and demagnetising fields of thin films and nanostructures. The system is based on a 7 Tesla superconducting magnet cryostat ('_MagLab - 8̻, Oxford Instruments) with a variable temperature insert ( 1.4-300K)._ The temperature is maintained through a PID regulated needle valve maintaining minimum mechanical vibrations. The measurements are automated via a LabView interface and can be programmed to combine temperature-field-angle regimes. The cryostat has a capability to work with other experiments, including_ magneto-resistive measurements, using separate inserts and the corresponding electronic equipment.
