Abstract: | Stress measurements with sub-monolayer sensitivity are performed to investigate the correlation between mechanical film stress and magneto-elastic anisotropy in epitaxial ferromagnetic monolayers. The magneto-elastic coupling B1 of Fe(1 0 0) films is measured directly. Magnitude and sign of B1 deviate from the respective bulk value. A strain-dependent correction of the magneto-elastic coupling coefficient B1 describes the apparent thickness dependence of B1 for film thicker than 10 nm. For thinner films, the possible contribution of surface corrections is discussed to explain the almost constant B1. The implications of a modified magneto-elastic coupling for the anisotropy of ultrathin films is elucidated. |
