Elastic and relaxor behavior in nanocrystalline La-modified PZT-films

Abstract
By reduction of the dimensions of the crystallites of ferroelectric and relaxor ceramics in the nanoscale range, one expects significant changes in their properties. In the case of PLZT 8/65/35 as a typical relaxor material one would expect a quantitative change of the relaxor properties, while ferroelectric materials are expected to show relaxor behavior because their crystallites have a size comparable to the relaxors nanodomains. For electric, respectively dielectric and elastic investigations thin amorphous films of PLZT were produced by rf-sputtering at room temperature and different grain sizes in the nanoscale range were prepared by a subsequent annealing process.
