VSM Magnetometer
This liquid-based flow cryostat with a 14 T superconducting magnet (Cryogenic Ltd) provides a versatile and powerful device for both magnetic and electrical properties measurements in a wide range of temperatures (1.6K-375K). Magnetic moments are determined within the range 10-6-100 emu and AC susceptibility can be measured with a sensitivity of 10-7 emu/Gauss, in the frequency range 1 Hz-20 kHz with a phase setting accuracy of 0.1° which allows to study a wide variety of different materials. The module for electrical properties measurements has a single axis rotating probe (out of plane) allowing measurements at different angles. Electrical resistivity measurements can be performed in samples with resistance in the range from 100 nΩ to 1 GΩ.
This equipment is available to the scientific community, on the basis of research cooperation and co-authorship of publications in international scientific journals and presentations in Conferences.
