Geometry and Magnetism of Lanthanide Compounds

Abstract

Lanthanide single molecule magnets (Ln-SMMs) were still been considered as the exceptionally promising candidates in high-density data storage and quantum calculation although the single atom magnets with smaller size have been discovered. Recent developments that the intrinsic magnetic properties of Ln-SMMs can be preserved when deposited on the surface of substrates greatly inspired us to make more efforts in facilitating the above practical applications. It is well-known that the single molecule magnet (SMM) behavior is strongly dependent on the coordination environments experienced by the lanthanide ions. Here, we focus on the representative Ln-SMMs with different coordination geometries from the view of coordination numbers, discuss the methods of modulating ligand fields, highlight the importance of constructing predominant bonds, and explain the relationship between the geometry, crystal field, and molecular magnetisms.
