We report on the study of in-plane magnetic anisotropy and magnetization reversal in MBE grown ultrathin epitaxial Mo/Au/Co/Au magnetic films. We used a magneto-optical polar Kerr effect-based magnetometer and real-time data analysis using LabView software. A two-fold in-plane magnetic anisotropy symmetry was deduced from the shape analysis of the magnetization curves measured for various directions of in-plane applied magnetic field. The direction of easy magnetization axis in the sample plane is a result of a small, unintentional miscut of the sapphire substrate found by in-situ STM and X-ray diffraction measurements.
