Magnetic properties of biotite micas Journal of Applied

The magnetic behavior of eight samples of biotite and a lepidomelane was studied in the temperature range 1.5300 K and analyzed in relation to their chemical composition. The platy morphology of biotite facilitates magnetic measurements with the applied field either in the plane of the sheets (Xe⊥ ) or perpendicular to the plane (Xe∥).
