Using Faraday Rotation to Determine Internal Magnetic Properties

In studying a Faraday Effect, known as Faraday rotation, one looks at the change in polarization of incident laser beam through a sample in an external magnetic field, and links this to the internal magnetic properties of the sample’s material. This change in polarization can be measured by shining a laser of known polarization through the sample in the field, and then measuring the polarization angle of the emerging beam with a secondary polarizer and photometer. The polarization change is generally wavelength dependant, and this characteristic will also be investigated. The result of this research will be to develop a new experiment for the Advanced Physics Laboratory.
