Antiferromagnetic spintronics is a rapidly emerging field with the potential to revolutionize the way information is stored and processed. One of the key challenges in this field is the development of novel 2D antiferromagnetic materials. In this paper, the first on‐surface synthesis of a Co‐directed metal–organic network is reported in which the Co atoms are strongly antiferromagnetically coupled,...
Graphene Nanoribbons
This work studies the growth, characterization, and device integration of 5‐armchair graphene nanoribbons (GNRs). 5‐AGNRs are synthesized under ultrahigh vacuum conditions from Br‐ and I‐substituted precursors. In article number 2202301, Gabriela Borin Barin, Pascal Ruffieux, and co‐workers show that I‐substituted precursors and optimized initial precursor coverage quintuple the...
The electronic, optical, and magnetic properties of graphene nanoribbons (GNRs) can be engineered by controlling their edge structure and width with atomic precision through bottom‐up fabrication based on molecular precursors. This approach offers a unique platform for all‐carbon electronic devices but requires careful optimization of the growth conditions to match structural requirements for successful...
Lanthanide Multinuclear Networks
In article number 2107073, Sofia O. Parreiras, David Écija, and co‐workers demonstrate the tuning of the electronic and magnetic properties of dinuclear lanthanide metal–organic networks by metal exchange while preserving the same structural architecture. The exchange between Er and Dy metallic centers leads to a shift in the energy level alignment and allows the...
The design of lanthanide multinuclear networks is an emerging field of research due to the potential of such materials for nanomagnetism, spintronics, and quantum information. Therefore, controlling their electronic and magnetic properties is of paramount importance to tailor the envisioned functionalities. In this work, a multidisciplinary study is presented combining scanning tunneling microscopy,...
Magnetic Anisotropy
The magnetism of lanthanide‐directed nanoarchitectures on surfaces can be drastically affected by small structural changes. In article number 2102753, Sofia Parreiras, Paolo Perna, David Écija, and co‐workers report the effect of the coordination environment in the reorientation of the magnetic easy axis of dysprosium‐directed metal‐organic networks on Cu(111). The authors show...
Taming the magnetic anisotropy of lanthanides through coordination environments is crucial to take advantage of the lanthanides properties in thermally robust nanomaterials. In this work, the electronic and magnetic properties of Dy‐carboxylate metal–organic networks on Cu(111) based on an eightfold coordination between Dy and ditopic linkers are inspected. This surface science study based on scanning...
