In this work the magneto-optical properties of the first stadium of the initial growth of a ferromagnetic material deposited on top of a substrate will we analyzed. Two different growth modes will be discussed: layer by layer and three dimensional growth mode. A comparison of the magneto-optical signal for the two growth modes will be presented for three different configurations of the applied magnetic field: magnetic field applied perpendicular to the layer (polar) and in the plane of the layer (transverse and longitudinal). The main results are: In the layer by layer growth mode, the intensity of the magneto-optical Kerr signal is a linear function of the thickness of the deposit layer and the magnetic moment of the layer (i.e., the intensity is a linear function the amount of deposit material for the three configurations). Therefore, the intensity of the magneto optical signal can be used to analyze the evolution of the magnetic moment of the layer as we increase the thickness. In the case of three dimensional growth mode, the intensity of the magneto-optical Kerr signal does not only depend on the magnetic moment of the layer, but also on the shape and amount of islands present in the layer. Contrary to the layer by layer growth mode the intensity of the magneto-optical properties is not a linear function of the amount of the deposited material and therefore can not be directly correlated with the magnetic moment.
