Abstract

In this paper, we report on the characterization of the magnetic properties of layered Fe/CoO/Fe(001) magnetic structures by means of Magneto-Optical Kerr Effect. Hysteresis loops were acquired on samples with variable CoO thickness, from 1 nm to 4 nm, and at different temperatures, from 30 K to room temperature. This characterization offers the opportunity of exploiting the differences in the layer-dependent sensitivity of Kerr rotation and Kerr ellipticity in order to disentangle the contribution of the different Fe layers in the hysteresis loops. Moreover, it allows us to give a detailed overview of the magnetic behavior of the trilayers.
