Large change in magneto-optical Kerr response and increase in perpendicular anisotropy were observed in ultrathin Co films on Pt(1 1 1) upon thermal annealing at elevated temperatures. Monitoring the film structure by using low-energy electron diffraction and Auger electron spectroscopy, these findings were found to be correlated to the Co–Pt alloy formation at interface.
