Metal Layers

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.

Abstract Using newly precipitated Cu(OH)2, o-phenanthroline and phosphoric acid as raw materials, two complicated Cu(II) compounds were obtained by one-pot method. They are double-nuclear Cu(II) 1, {[Cu2(phen)2(H2PO4)3][Cu2(phen)2(H2O)(H2PO4)3]}·2H2PO4·5H2O, and mononuclear Cu(II) 2, [Cu(phen)2(H2PO4)]4·4H3PO4·2HPO4·6H2O. The crystal structure analysis showed that the copper phosphate reacted with the neutral ligand o-phenanthroline to obtain the compounds with different structures. Phosphoric acid can exist in various forms in copper complexes, such as H3PO4, (H2PO4)1-, (HPO4)2-, and form a rich and colorful supramolecular interaction with water molecules. Hirschfeld surface analysis gives the types and regions of molecular interactions in crystals. It is of scientific significance to understand the reaction between transition metal phosphate and organic neutral ligand. The thermogravimetric and magnetic properties of compounds 1 and 2 were also reported. Magnetic analysis shows that supramolecular interactions and dipole-dipole interactions have great influence on the magnetic properties of two compounds. CCDC: 20565681 for 1; 2090334 for 2.
