摘要：

ME (magnetoelastic) effects frequently are held responsible for altered magnetic anisotropies of thin films. We show that at typical intrinsic stress values (> 0.1 GPa) the ME properties of thin films may deviate significantly from that described by the linear ME coupling constants of the bulk. Quantitative measurements on epitaxial Fe(001) films with a cantilever beam magnetometer provide a second order ME coupling constant of Fe, D-11 = 1.1 GJ/m(3), yielding for the first time an experimental bulk value of a magnetic element.
