Research Fields
A UHV-cantilever beam magnetometer was developed to study the mechanical and magnetic properties of thin and ultrathin films, which are both related to the growth and microstructure investigated by LEED and STM. As this tech- nique enables both measurements of intrinsic stress and magnetostriction, the magnetoelastic energy, which may be a dicisive parameter for magnetic anisotropies, can be determined with monolayer sensitivity. Recently film-stress- induced nonlinear behaviour of the magneto- elastic coupling constants of epitaxial Fe(001) was observed for the first time.
