Magnetometry, i.e. measurement of magnetic field and moment, of magnetic features of materials and of any physical parameters under controlled magnetic field, is a powerful, versatile and non-destructive way to characterize a wide range of raw and functionalised materials, as well as processes.

Magnetometry covers a broad range of measurement methods and tools. One of the goals of the European Magnetometry Network is to popularize magnetometry techniques in the whole scientific community and the general public. Therefore in the present section, we highlight some of the most common magnetometers which can be used both for fundamental research and R&D.

It includes measurements of magnetization, magnetic susceptibility, magnetization dynamics, but also characterization of the electrical transport properties of materials (resistance, magnetoresistance, Hall effect), thermal properties (specific heat, thermoelectric constant), magneto-optical properties (Kerr and Faraday effect).

All of these measurements allow to characterize the magnetic features of materials. Each techniques fits with specific types of sample (e.g. solid, liquid, thin film, powder), specific range of magnetic signal, specific sample sizes, etc.  It is important to be aware of the forces and limitations of each technique to insure the best usage of them.
