TbMnO₃ belongs to a class of rare earth manganites showing multiferroic behaviour. The strong magnetoelectric effect is expected to depend on the dimensionality of the system and on epitaxial strain in thin films. We have grown epitaxial TbMnO₃ films of different thicknesses (5-100nm) using Pulsed Laser Deposition on LaAlO₃ and SrTiO₃ substrates. We analysed the films by x-ray diffraction on a four-circle diffractometer and determined the twinings effects quantitatively. We will report on the thickness dependence of magnetization and electrical polarization as well as on scattering experiments using soft x-ray resonant magnetic scattering and polarized neutron reflectometry.
