Lake Shore’s Vibrating Sample Magnetometer systems (VSM) can measure all types of magnetic materials in bulk, powder, thin film, single crystal, and liquid form, and the latest 7400 series Vibrating Sample Magnetometer is the most sensitive VSM available today.
This VSM features a noise floor of 1 x 10-7 emu at 10 seconds/point sampling, 4 x 10-7 emu at 1 second per point and 7.5 x 10-7 emu at 0.1 seconds per point. In addition to providing the lowest noise floor, the 7400’s patented technology leads to a stability of 0.05% per day which surpasses the stability of any other commercial VSM.
Under full software automation it can measure and record hysteresis M(H) loops, torque curves, isothermal and DC demagnetisation remanence curves, and temperature dependent magnetic properties.
Models based on variable gap 4″, 7″ and 10″ electromagnets are available, providing field strengths to above 3 T. While variable gap magnets allow for easy reconfiguration of the magnet gap to accommodate large samples of up to 1″.
