Analytical platform for magnetic measurements
The instruments we use are adapted to the experimental specificities of paleomagnetism, archaeomagnetism and mineral magnetism studies. They constitutes one of the most complete sets of instruments in France and in the world. The laboratory regularly welcomes users from outside the IPGP, notably from other French and foreign university laboratories. Finally, the researchers of the lab carry out services and expertise for external institutions and companies.
Our equipments are housed in 4 lab rooms, including a special room that eliminates the Earth’s magnetic, at IPGP in Paris and on the site of the French Magnetic Observatory that the IPGP manages in Chambon-la-Forêt.
Magnetometers are used to measure the magnetisation of samples. Depending on the type of magnetometer used, these measurements are carried out in zero field or in an applied field up to 5 T, at room temperature or at temperatures varying between -271°C (2 K) and 800°C (1073 K). Magnetometers are also distinguished by the method of measurement acquisition.
The following instruments are available:
- 2G 755-HR – discrete sample (SQuID sensor)
- 2G 755-HR – multiple samples or u-channel (SQuID sensor)
- Quantum Design MPSM XL-5 EverCool (SQuID sensor)
- AGICO JR-6
- Inductometer for large samples
- Triaxe – 3 devices
- Princeton Measurements VSM / AGM Model 3900
