Abstract:

Results of investigations of structural and magnetic properties of Fe/Cr/Gd superlattices that differ in the thicknesses of the Cr interlayer have been reported. The insertion of the Cr interlayer between Gd and Fe layers has been found to lead to structural changes in Gd layers and the appearance of an additional fcc phase in them along with the main hcp phase. The new fcc phase is uniformly distributed across the thickness of the layer and is not localized near layer boundaries or in the center of Gd layers. Polarized-neutron reflectometry was used to show that the aforementioned structural changes are accompanied by a substantial (two-fold to threefold) decrease in the average magnetization of gadolinium over a wide temperature range. Near interfaces of the Gd layer, a layer appears that is two-to-three monatomic layers thick and characterized by increased magnetic moment.

Funding-Text	This study was performed in terms of the state assignment of Federal Agency for Scientific Organizations of Russia (theme Spin, no. 01201463330) and in part supported by the Russian Foundation for Basic Research (project no. 14-22-01063) and by the Ministry of Education and Science (contract no. 14 Z 50.31.0025). Polarized neutron reflectometry studies were performed using a NREX instrument at stationary FRM-II neutron reactor in the Heinz Maier-Leibnitz Center (Garching, Germany), which is exploited by the Max Planck Institute for Solid State Physics (Stuttgart, Germany).
