External magnetic field is technically set to any direction, (albeit though it has to be parallel to the surface of the sample positioned) and it would still not change the scattering geometry. It is observed that the last, the sample and the detector are usually fixed in this case. The magnetic field in each of the pole pieces is usually detected and developed around this setup. In the case of an experiment with the matrix form of analysis it is observed that a two circle goniometer would be used. This is the Bragg-bretano geometry meter.
An incident angle can be charged around 0 degree to 60 degree. The light passes between two Faraday cell units and these are called the rotator and the modulator and is finally seen through impact on a photodiode. Faraday cells used here are seen to be enclosed in a coil like surrounding and are in the direct production line of an axial field rod as implied in verdet’s law.
Three-dimensional identity of the magnetization is found to encompass many micro magnetic phenomena. From these data, there can be characterization of the magnetization processes. These are used to analyze the nanostructures that are found to be emboldened in the static and dynamic regimes. The scanning Kerr magnetometer is used for the purpose of the high numerical aperture. The microscope objective is that the incident light beam needs to be conclusively deviated from objective symmetry axis. Subsequent to this these are found to in-plane and out of plane In the cases of in plane it is known as the longitudinal Kerr effect and in the cases of out-of-plane it is known as the polar Kerr effect components. These are found in the magnetization vector that may be detected. Of these components are found to separate from each other by the exploitation of the symmetries that are found in the polar and longitudinal Kerr effects. Based on this four consecutive measurements are drawn and from this there can be three orthogonal components of the that are related to the magnetization vector found.
