Robust magnetic anisotropy of a monolayer of hexacoordinate Fe( ii ) complexes assembled on Cu(111)

TL;DR

This paper demonstrates that a monolayer of hexacoordinate Fe(II) complexes on Cu(111) exhibits robust magnetic anisotropy due to the ligand's rigid scaffold, despite environmental asymmetry.

Contribution

It introduces a method to achieve stable magnetic anisotropy in monolayer Fe(II) complexes using a tris pyrazolyl borate ligand.

Findings

Robust magnetic anisotropy observed in monolayer Fe(II) complexes.

Ligand scaffold maintains magnetic properties despite substrate asymmetry.

Potential for stable magnetic materials in thin-film applications.

Abstract

The tris pyrazolyl borate ligand imposes a rigid scaffold around Fe( ii ) ensuring a robust magnetic anisotropy when the molecules assembled as monolayers suffer from the dissymmetric environment of the substrate/vacuum interface.
