Dear Colleague,
We are looking for a high field torque magnetometer, that could aid in separating the paramagnetic and ferrimagnetic fabrics in rocks. Are there any particular models that you would recommend.
Thanks
Amar
Dear Colleague,
for distinguishing paramagnetic and ferromagnetic contributions to your sample, a stray field sensing Magnetometer might give ambiguous results. Both contributions add to the magnetic Signal. In contrast, you may consider a Torsion oscillation Magnetometer, which Comes with high sensitivity. For this type of Magnetometer only those components contribute that have a mechanical coupling of magnetization and sample, i.e. a strong magnetic anisotropy. This is typical predominantly for ferromagnets, such as Magnetite. A description of this Magnetometer can be found in: U. Gradmann et al., Appl. Phys. 10, 219 (1976).
