Abstract
A method for determining at least one property of magnetic matter includes: applying a magnetic field to magnetic matter; directing first light on the magnetic matter at a first set of incident angles; receiving a first set of signatures associated with the first light scattered from the magnetic matter; varying orientation of the magnetic matter with respect to the magnetic field; directing second light on the magnetic matter at a second set of incident angles; receiving a second set of signatures associated with the second light scattered from the magnetic matter; determining, by processing the first set and the second set of signatures according to a dispersion relation, at least one property of the magnetic matter.
