Fe/Tb multilayers of fixed Tb thickness (1.9 nm) and various Fe thichnesses (in the range 0.2-3.3 nm) have been prepared by rf-pulverization on Si(111) substrates. Conversion Electron Mössbauer Spectrometry was used to get information on the structure and the spin texture of the multilayers. Polar Kerr hysteresis loops have been used to obtain the global magnetic properties. The iron layers are amorphous up to 2.1 nm and the magnetic anisotropy lies in the plane of the layers above eTb/eFe=0. 9.
