Controlled hydrogen saturation is a promising method for controlling the structural and magnetic properties of rare-earth metal thin films. Optimum conditions for hydrogenation of gadolinium thin films have been determined to obtain the required phases: a solid solution of hydrogen in gadolinium or gadolinium hydrides GdH2 and GdH3. It has been shown that hydrogenation of the gadolinium layer can be carried out both through a catalytic surface layer of platinum and through a functional niobium layer, without using noble metals. By analyzing the structural changes in the films, the processes of guiding of these two types in Gd thin films have been compared. Keywords: X-ray diffractometry, X-ray reflectometry, hydrogen, gadolinium, gadolinium hydrides, thin film hydrogenation.
