There is a great interest in the properties of thin magnetic layers and quantum structures containing classical ferromagnets deposited on semiconductor substrates. In particular, structural and magnetic properties of bcc Fe films on GaAs and Si substrates have been extensively investigated in the past. However, up to now, little is known about the influence of hydrogen on the magnetic properties of systems involving such films.
The goal of the present studies was to look for the modification of the magnetic properties of Fe layers deposited in the hydrogen atmosphere and for the relation between the change in the magnetic properties and in the changes in the layer structure. Both 1000 A thick Fe layers (with and without hydrogen) and Fe/Fe:H multilayers were deposited in UHV sputtering system and characterized by X-ray diffraction at the Institute of Physics of the Polish Academy of Sciences in Warsaw. Magnetic properties of the samples were investigated by means of the magneto-optical Kerr effect (in Warsaw) and the neutron scattering at Laboratoire Leon Brillouin in Saclay (France). The spin-polarized neutron reflectometry and small-angle elastic neutron scattering were applied in order to check the presence of hydrogen in the investigated layers and to estimate the upper limit of its concentration. Results of our studies were discussed and compared with a few experimental data which can be found in the literature.
