Distribution of magnetic field intensity on surface of ferromagnetic specimen with specimen getting thinner

Contemporary achievements of the physics of surfaces allow to define dramatic differences between the surface layers and the underneath part of the same material. Even though there is a wide range of test methods and scientific findings, so far all the peculiarities of the surface phenomena have not been figured out. The article considers a hypothesis of the surface layer fractal structure. The hypothesis is based on the fact that the transition from a 3D plane to a 2D plane happens through a number of intermediary structures (transition or small-fraction layer). In order to check this hypothesis, we carried out an experiment aimed at studying the intensity of the magnetic field of a ferromagnetic specimen with the specimen getting thinner. The idea of the experiment was in the assumption that if the specimen has a certain thickness the surface layers will become comparable with the underneath material and this will influence the way the magnetic field intensity changes. The conducted measurements allowed to build a correlation between the magnetic field intensity components and the specimen thickness. The measurements showed that the thinner the specimen is, the ‘closer’ the correlation is. These findings display how the small fraction layer reacts to the change of the underneath material. This confirms it is possible to obtain information about the state of the structural material underneath by measuring the surface properties.
