Magnetization

Contacts: GABRIEL SEYFARTH (Grenoble)

 

Magnetization measurement is based on the principle of the Faraday balance, depicted above. A magnetic sample is placed on a suspended platform, inside a magnetic field gradient created by a ferromagnet. The magnetic force on the sample induces a displacement of the platform which is detected with a capacitance measurement.

 

Above we show an example of magnetization measurement in high magnetic field and low temperature in a Weyl semimetal. de Haas van Alphen quantum oscillations are measured up to the highest field when applied along the a-axis of the hexagonal structure.
