The SQUID magnetometer provides highly sensitive measurement of the magnetic moment of a sample depending on magnetic field (static and/or alternating) and temperature.
The magnetisation and magnetic susceptibility of the analysed substance analysed can easily be deduced from the measurements. It provides general information on magnetic and electronic behavior: insulating or conducting character, degree of oxidation of an ion, spin state, magnetic, insulating-metal or superconducting transitions, etc.
A wide range of samples and materials can be analyzed non-destructively, including powders, ceramics, crystals, amorphous materials, gels and thick films.

Study of materials for supercapacitors or batteries
Fe2WO6 nanoparticles have been prepared and studied at the Institut des Matériaux de Nantes Jean Rouxel to produce negative electrodes for supercapacitors. A comparative study of the magnetic properties, using SQUID magnetometry, of an unused electrode and the same electrode used during 10 000 charge/discharge cycles shows that the material does not amorphize or degrade during operating cycles.
Study of multiferroic materials
Magnetoelectric materials and multiferroics materials have potential applications in the field of information technology (information storage for multiferroics, in particular). Magnetometry, combined with dielectric measurements, can be used to detect the presence of multiferroic transitions in materials. For the compound MnWO4, we were able to show that the multiferroic transition is present not only in the microstructured ceramic material, but also in nanostructured ceramics (particle size: approx. 50 nm).
