Measurement of Verdet Constant for Some Materials
magneto-optical effect, polarization, magnetic field, verdet constant
Abstract
Verdet constant describes the strength of Faraday Effect for a particular material. The objective of this work was to measure the Verdet constant for different materials. The Verdet constant is measured by using the Faraday Effect which is a magneto-optical phenomenon; mean it describes the rotation of the plane of polarization of light with in a medium when it is placed in an external magnetic field. So this experiment determines the rotation of the plane of polarization with respect to the wavelength and the magnetic field. Reading observed through this experiment depicts a linear relationship between the angle of rotation and the magnetic field. The Verdet constant is determined to be at constant laser wavelength λ = 632.8nm
