Abstract:
Layered nanoheterostructures Fe|MgO|Cr|MgO|Fe is an artificial ferromagnetic material in which the exchange interaction of the magnetic moments of Fe layers through intermediate dielectric and metal layers can lead to magnetic configurations that are not realized in the well-studied Fe|MgO|Fe and Fe|Cr|Fe. In this work, we investigated the 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) (thickness t = 0.9 and 1.8 nm). Structural studies performed using X-ray diffractometry and high-resolution reflectometry confirmed the formation of a textured structure and revealed its well-defined layered character with sharp interlayer boundaries.
Keywords:
layered magnetic nanoheterostructures, interlayer magnetic ordering, polarized neutron reflectometry, giant tunneling magnetoresistance effect.
