Dynamics in thin films

The properties of low-dimensional structures are significantly different from those of corresponding bulk materials. This is a reason for a series of new and unexpected systems and/or methods invented in last years within the nanotechnology push. Particularly interesting systems with serious technological impact are hard-magnetic materials with high crystallographic anisotropy like FePt and FePd. Investigation of atomic mobility either as diffusion or as collective dynamics like phase transitions or domain-reorientation phenomena are in these structures a relatively new and sparsely examined field. Our intention is to study these selected systems by a number of methods exploiting synergy effects between different scientific fields in order to achieve knowledge about dynamics and ordering phenomena in FePt and FePd. Suitable tools for studies of surfaces and thin films are surface-sensitive methods like low energy electron diffraction (LEED), Auger electron spectroscopy (AES) and conversion electron Mössbauer spectroscopy (CEMS). Combining these methods with scanning tunnelling microscopy (STM) or highly resolving transmission electron microscopy (HRTEM), extensive studies of surface and thin film systems are feasible.
