We report studies of the linear and nonlinear magneto‐optical properties of epitaxial ultrathin Co films grown on sapphire substrates covered with Mo or Mo/Au buffers. Changes of the crystallographic symmetry and magnetization of buried interfaces were deduced from the magneto‐optical Kerr effect hysteresis loops and magnetization‐induced second‐harmonic generation (MSHG). Depending on the buffer, two‐fold (for Mo buffer) or six‐fold (for Mo/Au buffer) symmetries were observed in both inplane magnetic anisotropy and MSHG intensity. (© 2008 WILEY‐VCH Verlag GmbH & Co.
