Abstract

Structural studies of multilayer magnetic nanostructures formed by alternating layers of transition (Fe) and rare-earth (Gd) metals, which are placed into a hydrogen atmosphere at 100°C, are performed. The hydrogen absorption of rare-earth metals results in the formation of GdHx crystalline phases, the microstructural peculiarities of which are studied by X-ray diagnostics techniques and electron microscopy.
