2D Co‐Directed Metal–Organic Networks Featuring Strong Antiferromagnetism and Perpendicular Anisotropy

Abstract

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, while featuring a perpendicular magnetic anisotropy. This material is a promising candidate for future antiferromagnetic spintronic devices, as it combines the advantages of 2D and metal–organic chemistry with strong antiferromagnetic order and perpendicular magnetic anisotropy.

“…In recent years, the systematic development of two-dimensional (2D) molecule-based materials has become the focus of intense research owing to their unique physical and chemical properties. , Supramolecular self-assembly and coordination engineering with organic molecules on surfaces represent powerful bottom-up strategies for the efficient construction of 2D molecular materials suitable for catalysis, magnetism, semiconducting electronic devices, and so forth, ,− which can be for instance tailored to incorporate functional magnetic metal centers, such as Co, , Ho, and Dy . A major challenge in this field is to increase system stability by designing 2D materials via covalent on-surface synthesis.…”
