The polar and longitudinal Kerr effects constitute the group of longitudinal MO effects. Under certain conditions, variations of the intensity of linearly polarized reflected light are observed in the configuration of either the polar or longitudinal Kerr effect geometry [30]. [Pg.216]

The effect of M on the reflected light intensity is known as the Kerr effect. The polar Kerr effect refers to a situation in which the sample has a component of M normal to the surface and normal incidence illumination is used. The longitudinal Kerr effect is used when M is parallel to the surface and the illumination is oblique. [Pg.610]

The geometrical arrangement indicates the relationship to the magneto-optical Kerr effect (MOKE). MCDAD corresponds to the longitudinal, MLDAD to the transversal MOKE. Additionally, the Earaday effect can be included it is the analogue to the magnetic circular dichroism in absorption (XMCD). [Pg.8]

In the Kerr effect, the polarisation rotation can be expressed by a relation similar to Eq. (4.72), except that it is independent of specimen thickness. The Kerr effect can be observed in three geometries polar, longitudinal and transverse, shown in Fig. 4.68. The rotation angle is largest in the polar geometry, where magnetisation is perpendicular to the specimen surface. [Pg.183]

The longitudinal (meridional) Kerr effect means both the rotation of polarization plane and appearance of the ellipticity when a linearly polarized light... [Pg.215]

MO Kerr effects are used to observe the domain structure of opaque materials. If the magnetization vector is perpendicular to the sample plane, then the polar Kerr effect is utilized. If the magnetization lies in the sample plane, then structure images can be obtained either in the longitudinal geometry with polarizers or in the transverse geometry without polarizers. [Pg.216]
