Magnon circular birefringence: polarization rotation of spin waves …

WebSuch a wave can be constructed via a superposition of right- and left-hand circularly polarized waves of equal amplitudes. So, the wave electric field can be written (1179) ... This effect is known as Faraday rotation. It is clear, from the above expression, that the rate of advance of the polarization angle with distance travelled by the wave ... WebThe Faraday effect describes the rotation of light polarization as it passes through a magnetic medium. The sense of rotation was found to reverse as the magnetization in the medium is switched. In 1877, Kerr observed a similar phenomenon to the Faraday effect when a linearly polarized light is reflected from a magnetic sample, later known as MOKE. magazines television newspapers
