Layered nanoheterostructure Fe|MgO|Cr|MgO|Fe is an artificial ferromagnetic material in which exchange interaction of magnetic moments in the iron layers through intermediate dielectric and metal layers can lead to magnetic configurations which do not appear in well-studied systems Fe|MgO|Fe and Fe|Cr|Fe. In this work correlations of the structural and magnetic properties of layered nanoheterostructures Fe(10 nm)|MgO(1.5 nm)|Cr( t nm)|MgO(1.5 nm)|Fe(7 nm) (with the thickness t being 0.9 and 1.8 nm) were studied. Structural studies made using high-resolution X-ray diffractometry and reflectometry proved the formation of a texturized structure and revealed its prominent layered character with clear interfaces between the layers.
