Abstract

Mossbauer spectroscopy (MS) and magnetooptical studies of RF-sputtered Tb_xFe_100-x (10<x<34) films were carried out. Spectra were measured at room temperature in a transmission geometry. All the spectra were fitted to a hyperfine field H_n distribution. The average iron magnetic moment μ_Fe over the whole distribution was obtained for a wide range of Tb-Fe film composition. The correlation between MS and magnetooptical data was studied. The effective values of the angle between the film normal and direction for Fe atom moments μ_Fe were obtained. Possible reasons for iron moments divergence from the film normal are discussed
